DESCRIPTION

The EV28163-Q-00A Evaluation Board is

designed to demonstrate the capabilities of

MPS’ MP28163.

The MP28163 is a highly efficient, low

quiescent current Buck-Boost converter, which

operates from input voltage above, below and

equal to the output voltage. The device

provides power solution for products powered

by a one-cell Lithium-Ion or multi-cell alkaline

battery applications where the output voltage is

within battery voltage rang.

The MP28163 operates with input voltage from

2V to 5.5V to provide adjustable output voltage

(1.5V to 5V), and is available in QFN10-3x3mm

package.

QUICK START GUIDE

1. Preset the load to some value, e.g. 0.5A, notice that the MP28163 may enter SCP hiccup if starting

up with a heavier load due to the secondary current limit which is for inrush protection..

2. Connect the positive and negative terminals of the load to the VOUT and GND pins, respectively.

3. Preset the power supply output voltage (2~5.5V), and then turn off the power supply.

4. Connect the positive and negative terminals of the power supply output to the VIN and GND pins,

respectively.

5. Turn on the power supply. The MP28163 demo board will automatically start up.

6. To use the Enable function, remove the jumper JP1, apply a digital input to the EN pin. Drive EN

higher than 1.2V to turn on the regulator or less than 0.4V to turn it off.

7. To use MODE pin for PSM operation, please turn off Vin then connect the jumper JP2 to GND.

8. If other output voltage is preferred, The output voltage VOUT can be programmed by changing R1

and R2 according to below equation:

OUT FB

R2 R1 VV

=×

−

, where FB

V. Is typically 0.496V, and R1, R2’s units are in kΩ, VOUT ‘s unit is in V. The value of R2 is

recommended to be from 100 kΩthrough 180 kΩ. The recommended output voltage can be from

1.5V through 5V.
