DC/DC Converter
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.

PQ60260HTB10 Module
Control Features
• On/Off control referenced to input side (positive and
negative logic options are available)
• Remote sense for the output voltage compensates for
output distribution drops
• Output voltage trim permits custom voltages and voltage
margining
Protection Features
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection
• Thermal shutdown
Optional Features (full-feature)
• Active current share for N+1 and parallel applications
• External Clock Synchronization pin for better EMI char-
acteristics
• Startup Synchronization pin for more consistent start-up
sequence
• ORing FET drive supply for efficient ORing protection
