DC/DC Converter
The PQ60120QTA12 PowerQor⢠Tera quarter-brick
converter is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter that uses syn-
chronous rectification to achieve 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. All of the power and control
components are mounted to the multi-layer PCB substrate
with high-yield surface mount technology. Since the
PowerQor converter has no explicit thermal interfaces, it is
extremely reliable. The Tera series offers the maximum use-
able output current for any standard âquarter-brickâ module.
Operational Features
PQ60120QTA12 Module
⢠Ultra-high efficiency, 91% at full rated load current
⢠Delivers up to 12 amps of output current (144W) with
minimal derating - no heatsink required
⢠Wide input voltage range: 35V â 75V, with 100V
100ms input voltage transient capability
⢠Fixed frequency switching provides predictable EMI per-
formance
⢠No minimum load requirement means no preload resis-
tors required
Mechanical Features
⢠Industry standard quarter-brick pin-out configuration
⢠Industry standard size: 1.45â x 2.3â (36.8x58.4mm)
⢠Total height less than 0.43â (10.9mm), permits better
airflow and smaller card pitch
⢠Total weight: 1.5 oz. (42 grams)
⢠Flanged pins designed to permit surface mount solder-
ing (avoid wave solder) using FPiP technique
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 protects
converter and load from permanent damage and conse-
quent hazardous conditions
⢠Active back bias limit prevents damage to converter
from external load induced pre-bias
⢠Output over-voltage protection protects load from dam-
aging voltages
⢠Thermal shutdown protects converter from abnormal
environmental conditions
Safety Features
⢠2000V, 30 M⦠input-to-output isolation provides
input/output ground separation
⢠UL/cUL 60950 recognized (US & Canada), basic insu-
lation rating
⢠TUV certified to EN60950
⢠Meets 72/23/EEC and 93/68/EEC directives which
facilitates CE Marking in userâs end product
⢠Board and plastic components meet UL94V-0 flammabil-
ity requirements
