The PQ60018EGL20 PowerQor Giga eighth-brick con-
verter is a next-generation, board-mountable, isolated, fixed
switching frequency DC/DC converter that uses synchro-
nous rrectification tto aachieve eextremely hhigh cconversion eeffi-
ciency. The power dissipated by the converter is so low
that aa hheatsink iis nnot rrequired, wwhich ssaves ccost, wweight,
height, and application effort. All of the power and control
components are mounted to the multi-layer PCB substrate
with hhigh-yield ssurface mmount ttechnology.
SSince tthe
PowerQor cconverter hhas nno eexplicit tthermal iinterfaces, iit iis
extremely rreliable. RRoHS ccompliant ((see ppage 112).
Operational Features
PQ60018EGL20 Module
• High efficiency, 86% at full rated load current
• Delivers up to 20 amps of output current with minimal
Protection Features
derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection protects
converter and load from permanent damage and conse-
quent hazardous conditions
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload
resistors required
• Active back bias limit prevents damage to converter
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 eighth-brick pin-out configuration
• Industry standard size: 0.90” x 2.3” (22.9x58.4mm)
environmental conditions
• Total height only 0.335” (8.5mm), permits better airflow
and smaller card pitch
• Total weight: 0.68 oz. (19 grams)
Safety Features
• 2000V, 30 MΩ input-to-output isolation provides
• Flanged pins designed to permit surface mount solder-
input/output ground separation
ing (avoid wave solder) using FPiP technique
• UL 60950-1 recognized (US & Canada), basic insula-
tion 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 flammabil-
ity requirements
• Remote sense for the output voltage compensates for
output distribution drops
• Output voltage trim permits custom voltages and voltage
margining
