Advanced Data Sheet: Veta iHA48060A012V*, 1.2V/60A Output Half Brick
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)
