Technical S pecification BQ55090ETA27 35-55V Input I nput 9.6V Output 27A Current 2000Vdc Isolation Eighth-brick DC Bus Conver ter The BusQor® BQ55090ETA27 bus converter is a next-generation, board-mountable, isolated, fixed switching frequency D C / D C c o n ve r t e r t h a t u s e s s y n c h r o n o u s r e c t i f i c a t i o n t o 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 48V to a 9.6V intermediate bus with no regulation in a standard “eighth-brick” module. BusQor converters are ideal for creating the mid-bus voltage required to drive pointof-load (non-isolated) converters in intermediate bus architectures. RoHS compliant (see page 12 ). Bus Conver ter Operational Features • Ultra-high efficiency, >95% at full rated load current • Delivers up to 27 amps of output current with minimal derating - no heatsink required • Input voltage range: 35V – 55V provides 6.5-11V bus for distributed power architectures • Fixed frequency switching provides predictable EMI performance BQ55090ETA27 Module Pr otection Features • Input under-voltage lockout and over-voltage shutdown protects against abnormal input voltages • Output current limit and short circuit protection (auto recovery) • Output over-voltage protection • Thermal shutdown Mechanical Features • Industry standard eighth-brick bus converter pin-out • Industry standard size: 0.90” x 2.3” x .484” (22.9x58.4x11.76mm) • Total weight: 0.7 oz. (20 grams) • Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique Safety Features • 2000V, 30 MW input-to-output isolation • UL/cUL 60950-1 recognized (US & Canada), basic insulation rating • TUV certified to EN60950-1 • Meets 72/23/EEC and 93/68/EEC directives • Meets UL94V-0 flammability requirements Contr ol Features • On/Off control referenced to input side (positive and negative logic options available) Product # BQ55090ETA27 Phone 1-888-567-9596 www.synqor.com Doc.# 005-2BE559C Rev.
