PQ60025QML15 Datasheet, PDF (1/13 Pages) SynQor Worldwide Headquarters – 15 Amp, No Heatsink, Isolated DC/DC Converter

Technical Specification
Quarter
Brick
48Vin 2.5Vout 15A
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.
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
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
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

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 MΩ 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
