描述 Description

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).

特性 Features

操作特性
• 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
机械特征
• 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
控制功能
• On/Off control referenced to input side (positive and negative logic options are available)
安全特性
• 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
保护功能
• 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 consequenthazardous 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
