Si nce the P ower Q or c on ve rt er h a s no exp l icit th er ma l int er fa ces , it is ex tr emel y 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
PQ60033EGL20 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
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
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
