iHG48 Series DC-DC Power Modules
48V nput, 3.3V / 70A Output
Half-Brick
The Xeta

iHG48 Series power modules operate
over a wide 6 – 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: 2 1W
• 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

Thermal measurement location – top view
The thermal curves provided are based upon measurements made in TDK Innoveta’s experimental test setup that is
described in the Thermal Management section. Due to the large number of variables in system design, TDK Innoveta
recommends that the user verify the module’s thermal performance in the end application. The critical component
should be thermo-coupled and monitored, and should not exceed the temperature limit specified in the derating curve
above. It is critical that the thermocouple be mounted in a manner that gives direct thermal contact otherwise significant
measurement errors may result.
