Low IQBoost/SEPIC/

Inverting Converter

with 1A, 60V Switch

The LT

8330 is a current mode DC/DC converter capable

of generating either positive or negative output voltages

using a single feedback pin.It can be configured as a

boost, SEPIC or inverting converter consuming as low as

6µA of quiescent current.Low ripple Burst Mode opera-

tion maintains high efficiency down to very low output

currents while keeping the output ripple below 15mV in

a typical application.The internally compensated current

mode architecture results in stable operation over a wide

range of input and output voltages.Integrated soft-start

and frequency foldback functions are included to control

inductor current during start-up.The 2MHz operation

combined with small package options,enables low cost,

area efficient solutions.

pin FuncTions

EN/UVLO: Shutdown and Undervoltage Detect Pin.The

LT8330 is shut down when this pin is low and active

when this pin is high.Below an accurate 1.6V threshold

the part enters undervoltage lockout and stops switching.

This allows an undervoltage lockout (UVLO) threshold to

be programmed for system input voltage by resistively

dividing down system input voltage to the EN/UVLO pin.

An 80mV pin hysteresis ensures part switching resumes

when the pin exceeds 1.68V. EN/UVLO pin voltage below

0.2V reduces VIN current below 1µA. If shutdown and

UVLO features are not required,the pin can be tied directly

to system input.

FBX: Voltage Regulation Feedback Pin for Positive or

Negative Outputs.Connect this pin to a resistor divider

between the output and GND.FBX reduces the switching

frequency during start-up and fault conditions when FBX

is close to GND.

GND: Ground Connection for the LT8330. The DFN pack-

age has the best thermal performance due to an exposed

pad (Pin 9) on the bottom of the package.This exposed

pad must be soldered to a ground plane.Pin 5of the DFN

package (and Pin 2of the TSOT package)should also be

connected to a ground plane.The ground plane should be

connectedtolargecopperlayerstospreadheatdissipated

NC: No Internal Connection. Tie directly to local ground.

SW: The Output of Internal Power Switch.Minimize the

metal trace area connected to this pin to reduce EMI.

VIN: Input Supply.This pin must be locally bypassed.Be

sure to place the positive terminal of the input capacitor as

close as possible to the VIN pin,and the negative terminal

as close as possible to the GND pin.

operaTion

The LT8330 uses a fixed frequency,current mode control

scheme to provide excellent line and load regulation.Op-

eration can be best understood by referring to the Block

Diagram.An internal 2MHz oscillator turns on the internal

power switch at the beginning of each clock cycle.Current

inthe inductor thenincreasesuntil the currentcomparator

trips and turns off the power switch.The peak inductor

current at which the switch turns off is controlled by the

voltageonthe internal VC node.The error amplifier servos

the VC node by comparing the voltage on the FBX pin with

an internal reference voltage (1.60V or –0.80V, depending

on the chosen topology). When the load current increases

it causes a reduction in the FBX pin voltage relative to

the internal reference.This causes the error amplifier to

increase the VC voltage until the new load current is satis-

fied. In this manner,the error amplifier sets the correct

peak switch current level to keep the output in regulation.

The LT8330 is capable of generating either a positive or

negative output voltage with a single FBX pin.It can be

configured as a boost or SEPIC converter to generate a

positive output voltage,or as an inverting converter to

generate a negative output voltage.When configured as

a boost converter,as shown in the Block Diagram,the

FBX pin is pulled up to the internal bias voltage of 1.60V

by a voltage divider (R1 and R2) connected from VOUT

to GND.Amplifier A2becomes inactive and amplifier A1

performs (inverting) amplification from FBX to VC.When

the LT8330 is in an inverting configuration,the FBX pin

is pulled down to –0.80V by a voltage divider from VOUT

to GND.Amplifier A1becomes inactive and amplifier A2

performs (non-inverting) amplification from FBX to VC.

If the EN/UVLO pin voltage is below 1.6V, the LT8330

entersundervoltagelockout (UVLO),and stopsswitching.

When the EN/UVLO pin voltage is above 1.68V (typical),

the LT8330 resumes switching.If the EN/UVLO pin volt-

age is below 0.2V, the LT8330 only draws 1µA from VIN.

To optimize efficiency at light loads,the LT8330 operates

in Burst Mode operation in light load situations.Between

bursts, all circuitry associated with controlling the output

switch is shut down,reducing the input supply current

to 6µA.

ACHIEVING ULTRALOW QUIESCENT CURRENT

To enhance efficiency at light loads the LT8330 uses

a low ripple Burst Mode architecture.This keeps the

output capacitor charged to the desired output voltage

while minimizing the input quiescent current and output

ripple.In Burst Mode operation the LT8330delivers single

small pulses of current to the output capacitor followed

by sleep periods where the output power is supplied by

the output capacitor.While in sleep mode the LT8330

consumes only 6µA.

As the output load decreases,the frequency of single cur-

rent pulses decreases (see Figure 1) and the percentage

of time the LT8330 is in sleep mode increases,resulting

in much higher light load efficiency than for typical con-

verters. To optimize the quiescent current performance

at light loads,the current in the feedback resistor divider

must be minimized as it appears to the output as load

current. In addition,all possible leakage currents from Figure 1. Burst Frequency vs Load Current

applicaTions inForMaTion

the output should also be minimized as they all add to the

equivalent output load.The largest contributor to leakage

current can be due to the reverse biased leakage of the

Schottky diode (see Diode Selection in the Applications

Information section).

applicaTions inForMaTion

While in Burst Mode operation the current limit of the

switch is approximately 240mA resulting in the output

voltage ripple shown in Figure 2. Increasing the output

capacitance will decrease the output ripple proportionally.

As the output load ramps upward from zero the switch-

ing frequency will increase but only up to the fixed 2MHz

defined by the internal oscillator as shown in Figure 1. The

output load at which the LT8330 reaches the fixed 2MHz

frequency varies based on input voltage,output voltage,

and inductor choice.

Figure 2. Burst Mode Operation

PROGRAMMING INPUT TURN-ON AND TURN-OFF

THRESHOLDS WITH EN/UVLO PIN

The EN/UVLO pin voltage controls whether the LT8330 is

enabled or is in a shutdown state.A 1.6V reference and a

comparatorA6withbuilt-inhysteresis(typical80mV)allow

the user to accurately program the system input voltage

at which the IC turns on and off (see the Block Diagram).

The typical input falling and rising threshold voltages can

be calculated by the following equations:

VIN(FALLING,UVLO(–)) = 1.60 •(R3+R4)/R4

VIN(RISING, UVLO(+)) = 1.68 •(R3+R4)/R4

VIN current is reduced below 1µA when the EN/UVLO pin

voltage is less than 0.2V. The EN/UVLO pin can be con-

nected directly to the input supply VIN for always-enabled

operation. A logic input can also control the EN/UVLO pin.

When operating in Burst Mode operation for light load

currents, the current through the R3and R4network can

easily be greater than the supply current consumed by the

LT8330. Therefore,R3and R4should be large enough to

minimize their effect on efficiency at light loads.

INTVCC REGULATOR

A low dropout (LDO) linear regulator,supplied from VIN,

produces a 3V supply at the INTVCC pin.A minimum 1µF

low ESR ceramic capacitor must be used to bypass the

INTVCC pin to ground to supply the high transient currents

required by the internal power MOSFET gate driver.

No additional components or loading is allowed on this

pin. The INTVCC rising threshold (to allow soft start and

switching) is typically 2.6V. The INTVCC falling threshold

(to stop switching and reset soft start) is typically 2.5V.

DUTY CYCLE CONSIDERATION

The LT8330 minimum on-time,minimum off-time and

switching frequency (fOSC)define the allowable minimum

and maximum duty cycles of the converter (see Minimum

On-Time, Minimum Off-Time,and Switching Frequency

in the Electrical Characteristics table).

Minimum Allowable Duty Cycle =

Minimum On-Time(MAX) •fOSC(MAX)

Maximum Allowable Duty Cycle =

1 – Minimum Off-Time(MAX) •fOSC(MAX)

Therequired switch duty cycle range for a Boost converter

operating in continuous conduction mode (CCM) can be

calculated as:

DMIN = 1– VIN(MAX)/(VOUT + VD)

DMAX = 1– VIN(MIN)/(VOUT + VD)

where VDis the diode forward voltage drop. If the above

duty cycle calculations for a given application violate the

minimum and/or maximum allowed duty cycles for the

LT8330, operation in discontinuous conduction mode

(DCM) might provide a solution.For the same VIN and

VOUT levels,operation in DCM does not demand as low a

duty cycle as in CCM.DCM also allows higher duty cycle

operation than CCM.The additional advantage of DCM is

the removal of the limitations to inductor value and duty

cycle required to avoid sub-harmonic oscillations and the

right half plane zero (RHPZ). While DCM provides these

benefits,thetrade-offishigherinductorpeakcurrent,lower

available output power and reduced efficiency.

SETTING THE OUTPUT VOLTAGE

The output voltage is programmed with a resistor divider

from the output to the FBX pin.Choose the resistor values

for a positive output voltage according to:

R1 = R2 •(VOUT/1.60V – 1)

Choose the resistor values for a negative output voltage

according to:

R1 = R2 •(|VOUT|/0.80V – 1)

The locations of R1and R2are shown in the Block Dia-

gram. 1% resistors are recommended to maintain output

voltage accuracy.

Higher-valueFBXdividerresistorsresultinthelowestinput

quiescent current and highest light-load efficiency.FBX

divider resistors R1and R2are usually in the range from

25k to 1M. Most applications use a phase-lead capacitor

from VOUT to FBX in combination with high-value FBX

divider resistors (see Compensation in the Applications

Information section).

SOFT-START

The LT8330 contains several features to limit peak switch

currents and output voltage (VOUT)overshoot during

start-up or recovery from a fault condition.The primary

purpose of these features is to prevent damage to external

components or the load.

High peak switch currents during start-up may occur in

switching regulators.Since VOUT is far from its final value,

the feedback loop is saturated and the regulator tries to

chargetheoutputcapacitorasquicklyaspossible,resulting

in large peak currents.A large surge current may cause

inductor saturation or power switch failure.

The LT8330 addresses this mechanism with an internal

soft-start function.As shown in the Block Diagram,the

soft-start function controls the ramp of the power switch

current by controlling the ramp of VC through M2. This

allowstheoutputcapacitortobechargedgraduallytoward

its final value while limiting the start-up peak currents.

Figure 3 shows the output voltage and supply current for

the first page Typical Application.It can be seen that both

the output voltage and supply current come up gradually.

Figure 3. Soft-Start Waveforms

INTVCC undervoltage (INTVCC < 2.5V) and/or thermal

lockout (TJ> 170°C) will immediately prevent switching,

will reset the internal soft-start function and will pull down

VC. Once all faults are removed,the LT8330 will soft-start

VC and hence inductor peak current.

FREQUENCY FOLDBACK

During start-up or fault conditions in which VOUT is very

low, extremely small duty cycles may be required to

maintain control of inductor peak current. The minimum

on-timelimitationofthepowerswitchmightpreventthese

low duty cycles from being achievable.In this scenario

inductorcurrentrisewillexceedinductorcurrentfallduring

each cycle,causing inductor current to ‘walk up’beyond

the switch current limit.The LT8330 provides protection

from this by folding back switching frequency whenever

FBX pin is close to GND (low VOUT levels). This frequency

foldbackprovidesalargerswitch-offtime,allowinginductor

current to fall enough each cycle (see Normalized Switch-

ing Frequency vs FBX Voltage in the Typical Performance

Characteristics section).

THERMAL LOCKOUT

If the LT8330 die temperature reaches 170°C (typical),

the part will stop switching and go into thermal lockout.

When the die temperature has dropped by 5°C (nominal),

the part will resume switching with a soft-started inductor

peak current.
