Isolation
Half-Brick
DC-DC Converter
The PQ50073HZB60 PowerQor Zeta Half-Brick
converter is a next-generation, board-mountable,
isolated, fixed switching frequency DC/DC converter.
The Zeta series offers industry leading power density
for standard isolated DC/DC converters with both a
wide input range and a tightly regulated output.
Targeted for use in intermediate bus architectures,
this module supplies an isolated step down voltage
from 44-52V to 7.3V and provides 2,250Vdc isolation,
tolerance of output current transients up to 85A, and
more available power and higher efficiency than most
competitive bus converters. RoHS compliant (see last
page).
