DC/DC Converter
The PQ40033QGA25 PowerQor^™ Giga quarter-brick
converter is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter that uses syn-
chronous rectification to achieve extremely high conver-
sion 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-layer
PCB substrate with high-yield surface mount technology for
greater reliability. The PQ40 module offers a wide input
voltage range to cover both 24V and 48V applications.
RoHS Compliant (see page 12).
Operational Features
• High efficiency, 88.5% at full rated load current
• Delivers up to 25 amps of output current (82W) with
minimal derating - no heatsink required
• Ultra wide input voltage range: 18V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI per-
formance
• No minimum load requirement means no preload resis-
tors required
Mechanical Features
• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height only 0.43” (10.9mm), permits better airflow
and smaller card pitch
• Total weight: 1.2 oz. (34 grams)
• Flanged pins designed to permit surface mount solder-
ing (avoid wave solder) using FPiP technique
Control 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

Protection 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
Safety Features
• 2000V, 30 MΩ input-to-output isolation provides
input/output ground separation
• UL/cUL 60950-1 recognized (US & Canada), basic
insulation 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 flamma-
bility requirements
