Operational Features
• High efficiency, 89% at half load, >87% at full load
• Delivers up to 20 amps of output current (66W) 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
PQ60033EGL20 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 MW input-to-output isolation provides
input/output ground separation
• UL 60950-1 recognized (US & Canada), basic insula-
tion rating
• TUV certified to EN60950-1
• 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
