48Vin 5.3Vout 30A
30 Amp, No Heatsink, Isolated DC/DC Converter
The PQ48053HTA30 PowerQor™ Tera converter is a
next-generation, board-mountable, isolated,fixed switch-
ing frequency DC/DC converter that uses synchronous
rectification to achieve extremely high conversion effi-
ciency. 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 convert-
ers offer the maximum useable output current for any
standard “half-brick” module.
PQ48053HTA30 Module
