DC-DC Converter
The PQ40120QGx08 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 offers a wide input
voltage range to cover both 24V and 48V applications.
RoHS compliant (see the last page).
Operational Features
• High efficiency, 90% at full rated load current
• Delivers 8.33A full power with minimal derating - no heatsink required
• Ultra wide input voltage range: 18-75V, with 100V 100ms input
• Fixed frequency switching provides predictable EMI
• No minimum load requirement
