Product Details

The PQ60033QPA45 PowerQor® Peta 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 Peta series offers industry leading output currents for any standard quarter-brick module. RoHS compliant (see page 13).

Operational Features

• Ultra-high efficiency, 90% at full load current
• Delivers up to 45 amps of output current 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 quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.45” (11.4mm), 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

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

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 flammability requirements

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
