DC/DC Converter
The PQ60480QTA03 PowerQor^® Tera quarter-brick
converter is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter. The power dis-
sipated 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 useable output current for any standard
“quarter-brick” module. RoHS Compliant (see page 12).
Operational Features
• Ultra-high efficiency, 92% at full rated load current
• Delivers up to 3 amps of output current (144W) with
minimal derating - no heatsink required
• 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
Mechanical Features
• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.43” (10.9mm), permits better
airflow and smaller card pitch
• Total weight: 1.5 oz. (42 grams)
• Flanged pins designed to permit surface mount soldering
(allows to avoiding 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 MW input-to-output isolation provides
input/output ground separation
• UL/cUL 60950-1 recognized (US & Canada), basic
insulation rating
• TUV certified to EN60950-1
• Meets 72/23/EEC and 93/68/EEC directives which
facilitates CE Marking in user’s end product
• Board and plastic components meet UL94V-0 flammabil-
ity requirements
