Technical Specification
48Vin 2.5Vout 15A
Quarter
Brick
15 Amp, No Heatsink, Isolated DC/DC Converter
The PQ60025QML15 PowerQor Mega quarter-
brick converter is a next-generation, board-mountable,
isolated, fixed switching frequency DC/DC converter
that uses synchronous rectification to achieve very high
conversion efficiency. The power dissipated by the con-
verter 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 technology, yielding an extremely reliable prod-
uct that is less than 8.5mm in height. The Mega series
offer significant useable output current in an economi-
cal standard “quarter-brick” module.
PQ60025QML15 Module
Mechanical Features
Industry standard quarter-brick pin-out configuration
Industry standard size: 1.45” x 2.3”
Total height only 8.5mm (0.335”), permits better air-
flow and smaller card pitch, meets NTT reqs.
Total weight: 34 grams (1.2 oz.), lower mass great-
ly reduces vibration and shock problems
Operational Features
High efficiency, 85% at full rated load current
Delivers up to 15 amps of output current with mini-
mal derating - no heatsink required
Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient protection
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
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
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
