Data Sheet: Xeta iHG48070A033V, 3.3V/70A Output Half Brick Series
Platform Overview:
Xeta
48V Input, 3.3V / 70A Output
Half-Brick
iHG48 Series DC-DC Power Modules
The Xeta iHG48 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. The single
board open-frame type design with high
conversion efficiency (up to 92%), and superior
thermal performance make iHG series modules
ideally suited for high power, low air flow telecom
applications in demanding thermal environments.
A wide output voltage trim range, -50 to 10%, and
remote sensing are standard features enhancing
versatility.
Standard Features:
• RoHS compliant
• Standard Half Brick footprint
• Optimized output power: 231W
• Full load efficiency, 90% typical
• Wide output trim voltage range
• Up to 70A of true usable current
• Single board design
52A at 65°C, 200LFM (no base-plate)
• Monotonic start-up into a pre-biased
output bus
• Remote sense
• Basic insulation – 1500 Vdc
• Constant switching frequency
• Auto-recovery protection:
o Input UV protection
o Output over voltage
o Output over current
o Short circuit
o Thermal protection
• High reliability open frame, surface-
mount construction
• Open frame for improved thermal
management
• UL 60950 (US and Canada), VDE 0805,
CB scheme (IEC950), CE Mark
(EN60950)
• Multiple patents
Optional Features:
• Latched output over voltage protection
• Latched output over current protection
• Latched over temperature protection
• Base-plate
