DC-DC Converter
The PQ60033EGx20 PowerQor^® Giga eighth-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. RoHS compliant
(see page 12).
Operational Features
• High efficiency, 89% at half load, >87% at full load
• Delivers up to 20 amps of output current (66W) 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 performance
• No minimum load requirement means no preload resistors required
Mechanical Features
• Industry standard eighth-brick pin-out configuration
• Industry standard size: 0.90" x 2.3" (22.9x58.4 mm)
• Total height of the EGL is only 0.340" (8.64 mm), permitting better
airflow and smaller card pitch
• Total weight: 0.68 oz (19 g)
• Open frame units have flanged pins designed to permit surface
mount soldering (avoid wave solder) using FPiP technique
PQ60033EGL20 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
Safety Features
• 2000V, 30 MW input-to-output isolation provides input/output
ground separation
• UL 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 flammability requirements
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
