Technical Specification
48Vin 12Vout 12.5A
150 Watt, No Heatsink, Isolated DC/DC Converter
Mechanical Features
Industry standard pin-out configuration
Industry standard size: 2.3” x 2.4” (58.4x61.0mm)
Total height only 0.40” (10.2mm), permits better air-
flow and smaller card pitch
Total weight: 2.1 oz. (59 grams)
Safety Features
2000V, 30 M
input-to-output isolation
UL/cUL 60950 recognized (US & Canada), basic
insulation rating
TUV certified to EN60950
Meets 72/23/EEC and 93/68/EEC directives
Meets UL94V-0 flammability requirements
Operational Features
Ultra-high efficiency, >90% at full rated load current
Delivers up to 150 watts of output power with mini-
mal derating - no heatsink required
Wide input voltage range: 35V – 75V meets or
exceeds all 48V bus standards
Fixed frequency switching provides predictable EMI
performance
Protection Features
Input under-voltage lockout and over-voltage
shutdown protects against abnormal input voltages
Output current limit and short circuit protection
Output over-voltage protection
Thermal shutdown
Active back bias limit prevents damage to convert-
er from external load induced pre-bias
The PQ48120HGA12 PowerQor Giga converter
is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter that uses
synchronous rectification to achieve extremely high
conversion efficiency. The power dissipated by the
converter is so low that a heatsink is not required,
which saves cost, weight, height, and application effort.
The Giga series converters offer enhanced useable
output current in a standard “half-brick” module.
The Giga units also feature active current sharing
for N+1 and parallel applications.
PQ48120HGA12 Module
Control Features
On/Off control referenced to input side (positive
and negative logic options are available)
Remote sense for the output voltage compensates
for output distribution drops
Output voltage trim permits custom voltages and
voltage margining
Optional Features (Full-Feature modules)
Active current share for N+1 and parallel applications
External Clock Synchronization pin for better EMI
characteristics
Startup Synchronization pin for more consistent start-
up sequence
ORing FET drive supply for efficient ORing protection
