DC/DC Conver ter
The PQ60525HTA04 PowerQor
™
Tera converter is a next-
generation, board-mountable, isolated, fixed switching fre -
m
quency DC/DC converter that uses synchronous rectification
to achieve extremely high conversion efficiency. The module
is ideally suited to support the IEEE 802.3af standard for
Power Over LAN and VoIP applications. The Tera series
converters offer the maximum useable output current for any
standard “half-brick” module. The Tera units also feature
b
active current sharing for N+1 and parallel applications.
Operational Features
• Ultra-high efficiency, 92% at full rated load current
• Delivers up to 200 Watts of output power with mini-
mal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
PQ60525HTA04 Module
Contr ol 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
Mechanical Features
• Industry standard half-brick pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)

• Meets 72/23/EEC and 93/68/EEC directives
• Meets UL94V-0 flammability requirements
Pr otection 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
