Technical Specification
48Vin 2.5Vout 25A
Quarter
Brick
The PQ60025QGA25 PowerQor Giga quarter-
brick converter is a next-generation, board-mount-
able, 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. All of the power and
control components are mounted to the multi-layer
PCB substrate with high-yield surface mount tech-
nology. Since the PowerQor converter has no
explicit thermal connections, it is extremely reliable.
PQ60025QGA25 Module
25 Amp, No Heatsink, Isolated DC/DC Converter
Mechanical Features
Industry standard quarter-brick pin-out configuration
Industry standard size: 1.45” x 2.3”
Total height less than 0.40”, permits better airflow
and smaller card pitch
Total weight: 34 grams (1.2 oz.), lower mass great-
ly reduces vibration and shock problems
Safety Features
2000V, 10 M
input-to-output isolation provides
input/output ground separation
UL/cUL 60950 recognized (US & Canada), basic
insulation rating
TUV certified to EN60950
Meets 72/23/EEC and 93/68/EEC directives
which facilitates CE Marking in user’s end product
Board and plastic components meet UL94V-0 flam-
mability requirements
Operational Features
Ultra-high efficiency, 86% at full rated load current
Delivers up to 25 amps of output current with mini-
mal derating - no heatsink required
Wide input voltage range: 35V – 75V with 100V
100ms input voltage transient withstand
Fixed frequency switching provides predictable EMI
performance
No minimum load requirement means no preload
resistors required
Protection Features
Input under-voltage lockout disables converter at
low input voltage conditions
Output current limit and short circuit protection
protects converter from excessive load current or
short circuits
Output over-voltage protection protects load from
damaging voltages
Thermal shutdown protects converter from abnor-
mal environmental conditions
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
