DC/DC Converter
The PQ60050QTA30 PowerQor
®
Tera quarter-brick
converter is a next-generation, board-mountable,
isolated, fixed switching frequency DC/DC converter
that uses synchronous 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 useable output current for any
standard “quarter-brick” module.
RoHS compliant
(see page 13).
PQ60050QTA30 Module
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 consequent hazardous conditions
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Operational Features
• Ultra-high efficiency, >90% at full rated load current
• Delivers up to 30 amps of output current (150W) with
minimal derating - no heatsink required
• Wide input voltage range: 35 – 75V, with 100V 100ms
input voltage transient capability
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload
resistors 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 (avoid wave solder) using FPiP technique
Safety Features
• 2000 V, 30MΩ input-to-output isolation
• UL 60950-1:2003, basic insulation
• CAN/CSA-C22.2 No. 60950-1:2003
• EN60950-1:2001
• RoHS compliant (see page 13)
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

0.080” (2.03 mm) diameter standoff shoulders.
2) Pins 4 and 8 are 0.062” (1.57 mm) diameter with 0.100”
(2.54 mm) diameter standoff shoulders.
3) Other pin extension lengths available.
4) All Pins: Material - Copper Alloy
Finish - Matte Tin over Nickel plate
5) Undimensioned components are shown for visual reference only.
6) All dimensions in inches (mm)
Tolerances:
x.xx +/-0.02 in. (x.x +/-0.5mm)
x.xxx +/-0.010 in. (x.xx +/-0.25mm)
7) Weight: 2.4 oz. (68 g) typical
8) Workmanship: Meets or exceeds IPC-A-610C Class II
9) UL/TUV standards require a clearance greater than 0.04”
(1.02mm) between input and output for Basic insulation. This
issue should be considered if any copper traces are on the top side
of the user’s board. Note that the ferrite cores are considered part
of the input/primary circuit.
10) The flanged pins are designed to permit surface mount soldering
(allowing to avoid the wave soldering process) through the use of the
flanged pin-in-paste technique.
