Isolation
The PQ60025EGL25 PowerQor Giga eighth-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. Since the PowerQor
converter has no explicit thermal connections, it is
extremely reliable.
Protection Features

•
•
•
Input under-voltage lockout disables converter at low Vin conditions
Output current limit
Short circuit protection
Protection from permanent damage and hazardous conditions
Thermal shutdown protects converter from abnormal conditions
