Technical S pecification BQ55120ETL16 35-55V Input I nput 12V Output 192Watt Power 2000Vdc Isolation E ighth-brick Eighth-brick DC Bus Conver ter The BusQor™ BQ55120ETL16 bus 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. The BusQor series provides an isolated step down voltage from 35-55V to a 12V intermediate bus with no regulation in a standard “eighth-brick” module. BusQor converters are ideal for creating the mid-bus voltage required to drive point-of-load (non-isolated) converters in intermediate bus architectures. RoHS com pliant (see page 12 ). Operational Features • Ultra-high efficiency, >95% at full rated load current • Delivers up to 16 amps of output current (192W) with minimal derating - no heatsink required • Input voltage range: 35V – 55V provides 12V bus for distributed power architectures • Fixed frequency switching provides predictable EMI performance B us Bus Conver ter C onver BQ55120ETL16 Module Pr otection Features • Input under-voltage lockout and over-voltage shutdown protects against abnormal input voltages • Output current limit and short circuit protection • Thermal shutdown Mechanical Features • Industry standard eighth-brick bus converter pin-out • Industry standard size: 0.90” x 2.3” (22.9x58.4mm) • Total height only 0.320” (8.13mm), permits better airflow and smaller card pitch • Total weight: 0.7 oz. (20 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 available) • 2000V, 30 MΩ input-to-output isolation • UL/cUL 60950 recognized (US & Canada), basic insulation rating • TUV certified to EN60950 • Meets 72/23/EEC and 93/68/EEC directives • Meets UL94V-0 flammability requirements Safety Features Product # BQ55120ETL16 Phone 1-888-567-9596 www.synqor.com Doc.# 005-2BE552B Rev.
