Isolation
The PQ40150QGx07 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 highyield 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 last page.
Operational Features
• High efficiency, >90% at full rated load current
• Delivers up to 6.67A of output current 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.
PQ40150QGx07 Module
Protection Features
• Input under-voltage lockout disables converter at low input voltage
• Output current limit and short circuit protection protects converter
from excessive load current or short circuits
• 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 protectsconverer from abnormal
environmental conditions
Mechanical Features
