Platform Overview:

VetaiHA48 Series DC-DC Power Modules

48V Input, 1.2-28V/60A or 350W Output

Half-Brick

The VetaiHA48 Series power modules operate

over a wide 36 –75Vdc input voltage range and

provide one regulated dc output voltage that is

electrically isolated from the input. Its high

efficiency and superior thermal performance make

the VetaFamily of power modules ideally suited

for power-hungry applications in demanding

thermal environments. This rugged building block

is designed to serve as the core of your high

reliability system. A wide output voltage trim range

and remote sensing are standard features

enhancing versatility.

•Standard Half Brick footprint

•High efficiency, 83-93.5%

typical

•Wide output trim voltage

•Up to 60A of true usable current

•Industry-leading output power:

up to 350W

•Monotonic start-up

•Monotonic start-up into a pre-

biased output

•Basic insulation –1500 Vdc

•Constant switching frequency

•Auto-recovery protection:

oInput under and over

voltage

oCurrent limit

oShort circuit

oThermal limit

•Latched output over voltage

protection

•High reliability open frame,

surface-mount construction

•Baseplate for improved thermal

management

•UL 60950 (US and Canada),

VDE 0805, CB scheme

(IEC950), CE Mark (EN60950)

•Multiple patents pending

Optional Features:
