Specification
PQ60260HTB10
The PQ60260HTB10 PowerQor Tera converter is a next-
generation, board-mountable, isolated, fixed switching
frequency dc/dc converter that uses synchronous recti-
fication to achieve extremely high conversion efficiency.
The power dissipated by the converter is so low that a
heatsink is not required. However, this unit provides a
baseplate for clamshell applications and optional heat-
sinking in severe thermal environments. The Tera series
converters offer the maximum usable current output for
any standard “half-brick” module. The Tera units also
feature active current sharing for N+1 and parallel appli-
cations. RoHS Compliant see last page.
