Product Details

The PQ60120QEB20 PowerQor Exa Quarter-brick converter is a next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter. The Exa series offers industry leading power density for standard isolated DC/DC converters with both a wide input range and a tightly regulated output. Targeted for use in intermediate bus architectures, this module supplies an isolated step down voltage from 35-75V to 12V and provides more available power and higher efficiency than most competitive bus converters. This converter is available in baseplated versions. RoHS Compliant (see last page).

Operational Features

• Ultra-high efficiency, >94% at full rated load current, 94% typical at half rated load current
• Delivers up to 20A of output current (240W) 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
• Wide output voltage trim range (-50% to +5%), see trim section

Mechanical Features

• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.436” (11.06mm), permits better airflow and smaller card pitch
• Total weight: 2.4 oz. (69 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)

Safety Features

• 2250V, 30 MΩ input-to-output isolation provides input/output ground separation
• UL 60950-1 recognized (US & Canada), basic insulation rating
• TUV certified to EN60950-1

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 provides smooth startup with external load induced pre-bias
• Latching mode output over-voltage protection protects load from damaging voltages
• Thermal shutdown protects converter from abnormal environmental conditions
