Technical Specification
Half
Brick
48Vin 12Vout 12.5A
150 Watt, No Heatsink, Isolated DC/DC Converter
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 âhalf-brickâ module.
The Giga units also feature active current sharing
for N+1 and parallel applications.
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 â 75V meets or
exceeds all 48V bus standards
⢠Fixed frequency switching provides predictable EMI
performance
Mechanical Features
⢠Industry standard pin-out configuration
⢠Industry standard size: 2.3â x 2.4â (58.4x61.0mm)
⢠Total height only 0.40â (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
