60 Amp, No Heatsink, Isolated DC/DC Converter
The PQ60012HTA60 PowerQor™ Tera converter
is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter that uses
synchronous rectification toachieve 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.
The Tera series converters offer the maximum useable
output current for any standard “half-brick” module.
The Tera units also feature active current sharing for
N+1 and parallel applications.
