Brick
Half
48Vin 12Vout 13.8A
165 Watt, No Heatsink, Isolated DC/DC Converter
The PQ60120HTA14 PowerQor
™
Tera converter
is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter that uses
synchronous rectification toachieve extremely high
conversion efficiency. 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 converters offer the maximum useable
output current for any standard “half-brick” module.
The Tera units also feature active current sharing for
N+1 and parallel applications.
PQ60120HTA14 Module
Operational Features
• Ultra-high efficiency, 93% at full rated load current
• Delivers up to 165 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
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 convert-
er from external load induced pre-bias
• Output over-voltage protection
• Thermal shutdown
Mechanical Features
• Industry standard half-brick pin-out configuration
• Industry standard size: 2.3” x 2.4”
(58.4 x 61.0mm)
• Total height only 0.43”
(11.2mm),
permits better air-
flow and smaller card pitch
• Total weight: 2.6 oz.
(75 grams)
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
