Peta quarter-brick con -
b
verter is a next-generation, board-mountable, isolated,

m
fixed switching frequency DC/DC converter that uses syn -
chronous rectification to achieve extremely high conversion
efficiency. 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 components are mounted to the multi-llayer PCB
substrate with high-yield surface mount technology. Since
y
the PowerQor converter has no explicit thermal interfaces,
it is extremely reliable. The Peta series offers industry lead -
ing output currents for any standard quarter-brick module.

PQ60025QPA60 Module
Operational Features
• Ultra-high efficiency, 91% half load, 89% full load
• Delivers up to 60 amps of output current 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
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 quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.45” (11.4mm), permits better
airflow and smaller card pitch
• Total weight: 1.5 oz. (42 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/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 flamma-
bility 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 volt-
age margining
