The PQ60012QPA60 PowerQor Peta quarter-brick con-
verter is a next-generation, board-mountable, isolated, fixed
switching frequency DC/DC converter that uses synchronous
rectification tto aachieve eextremely hhigh cconversion eefficiency.
The power dissipated by the converter is so low that a
heatsink iis nnot rrequired, wwhich ssaves ccost, wweight, hheight,
and aapplication eeffort. AAll oof tthe ppower aand ccontrol ccompo-
nents aare mmounted tto tthe multi-layer PPCB ssubstrate wwith hhigh-
yield ssurface mmount ttechnology. SSince tthe PPowerQor ccon-
verter hhas nno eexplicit tthermal iinterfaces, iit iis eextremely rreli-
able. TThe PPeta sseries ooffers iindustry lleading ooutput ccurrents ffor
any standard quarter-brick module. RoHS Compliant (see
page 112).
PQ60012QPA60 Module
Operational Features
• Ultra-high efficiency, 87% half load, 84% full load
Protection Features
• Delivers up to 60 amps of output current with minimal
derating - no heatsink required
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection protects
converter and load from damage and consequent haz-
ardous conditions
• Wide input voltage range: 36V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
• Active back bias limit prevents damage to converter
• No minimum load requirement means no preload
resistors required
from external load induced pre-bias
• Output over-voltage protection protects load from dam-
aging voltages
Mechanical Features
• Thermal shutdown protects converter from abnormal
• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
environmental conditions
• Total height less than 0.45” (11.4mm), permits better
Safety Features
airflow and smaller card pitch
• Total weight: 1.5 oz. (42 grams)
• 2000V, 30 MΩ input-to-output isolation provides
input/output ground separation
• Flanged pins designed to permit surface mount solder-
ing (avoid wave solder) using FPiP technique
• UL/cUL 60950-1 recognized (US & Canada), basic
insulation rating
• TUV certified to EN60950-1
Control Features
• Meets 72/23/EEC and 93/68/EEC directives which
• On/Off control referenced to input side (positive and
negative logic options are available)
facilitates CE Marking in user’s end product
• Board and plastic components meet UL94V-0 flamma-
bility requirements
• Remote sense for the output voltage compensates for
output distribution drops
• Output voltage trim permits custom voltages and volt-
age margining
