Isolation
The PQ4008QGx09 PowerQor Giga quarter-brick
converter is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter that uses
synchronous 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-layer PCB
substrate with high-yield surface mount technology for
greater reliability. The PQ40 module offeres a wide input
voltage range to cover both 24V and 48V applications.
RoHS compliant (see last page).
Operational Features
• High efficiency, 90% at full rated load current
• Delivers up to 9A of output current (72W) 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 performance
• No minimum load requirement means no preload resistors required.
PQ40080QGx09 Module
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 damage and consequent hazardous conditions
• Active back bias limit prevents damage to converter from external
load induced pre-bias
• Output over-voltage protection protects load from damaging voltages
• Thermal shutdown protects converer from abnormal
Mechanical Features

Flanged pins designed to permit surface mount soldering,
avoid wave solder using FPiP technique on open frame units
Safety Features
• UL 60950-1:2007
• CAN/CSA-C22.2 No. 60950-1:2007
• EN60950-1/A12:2011
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
