The PQ60050EGL15 PowerQor
™
Giga eighth-brick con -
b
verter is a next-generation, board-mountable, isolated, fixed
g
m
switching frequency DC/DC converter that uses synchro -
nous rectification to achieve extremely high conversion effi -
ciency. 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 com -
ponents are mounted to the multi-llayer PCB substrate with
high-yield surface mount technology. Since the PowerQor
y
converter has no explicit thermal interfaces, it is extremely
reliable.
Operational Features
• High efficiency, >89% at full rated load current
• Delivers up to 15 amps of output current (75W) with
minimal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload
resistors required
PQ60050EGL15 Module
Pr otection Features
• 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
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection protects load from dam-
aging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Mechanical Features
• Industry standard eighth-brick pin-out configuration
• Industry standard size: 0.90” x 2.3” (22.9x58.4mm)
• Total height only 0.335” (8.5mm), permits better airflow
and smaller card pitch
• Total weight: 0.68 oz. (19 grams)
• Flanged pins designed to permit surface mount solder-
ing (avoid wave solder) using FPiP technique
Safety Features
• 2000V, 30 MΩ input-to-output isolation provides
input/output ground separation
• UL 1950 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 flammabil-
ity requirements
Contr ol 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
