The PQ60016QTA40 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. AAll 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 usable
output current for any standard “quarter-brick” module.
PQ60016QTA40 Module
Operational Features
• Ultra-high efficiency, 89% at half load, 85% at full load
• Delivers up to 40 amps of output current with minimal
Protection Features
derating - no heatsink required
• 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
• Wide input voltage range: 35V – 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
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection protects load from dam-
aging voltages
Mechanical Features
• Thermal shutdown protects converter from abnormal
• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
environmental conditions
• Total height less than 0.43” (10.9mm), permits better
airflow and smaller card pitch
• Total weight: 1.5 oz. (42 grams)
Safety Features
• 2000V, 30 MΩ input-to-output isolation provides
• Flanged pins designed to permit surface mount solder-
input/output ground separation
ing (avoid wave solder) using FPiP technique
• UL/cUL 60950 recognized (US & Canada), basic insu-
lation rating
Control Features
• TUV certified to EN60950
• On/Off control referenced to input side (positive and
negative logic options are available)
• Meets 72/23/EEC and 93/68/EEC directives which
facilitates CE Marking in user’s end product
• Remote sense for the output voltage compensates for
• Board and plastic components meet UL94V-0 flammabil-
ity requirements
output distribution drops
• Output voltage trim permits custom voltages and voltage
margining
