Data Sheet: Veta iHA48040A033V*, 3.3V/40A Output Half Brick Series

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 Features:

• 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:

o Input under and over

voltage

o Current limit
o Short circuit
o Thermal 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:

• Remote on/off (negative logic)

• Auto-recovery output over

voltage protection

• Short Thru-hole pins 2.79 mm
(0.110”)
