T h e P Q 3 0 0 3 3 E G A 2 0 P o w e r Qor ® M e g a e i g h t h - b r i c k 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 13). Operational Features
• High efficiency, 85% at full rated load current • Delivers up to 20 amps of output current with minimal derating - no heatsink required • Wide input voltage range: 18V – 60V, with 80V 100ms input voltage transient capability • Fixed frequency switching provides predictable EMI performance • No minimum load requirement means no preload resistors required
PQ30033EGA20 Module
Pr otection 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
Mechanical Features
• Industry standard eighth-brick pin-out configuration • Industry standard size: 0.90” x 2.3” (22.9x58.4mm) • Total height only 0.335” (8.5mm), permits better airflow and smaller card pitch • Total weight: 0.68 oz. (19 grams) • Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique
Contr ol 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
Product # PQ30033EGA20 Phone 1-888-567-9596 www.synqor.com
• 2000V, 30MΩ input-to-output isolation provides input/output ground separation • UL/cUL 60950-1 recognized (US & Canada) • 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
