SQ60120QPA28PYS中文资料SYNQOR数据手册PDF规格书

The BusQor® SQ60120QPA28 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 SQ BusQor series provides an isolated step down voltage from 48V to a semi-regulated 12V intermediate bus. BusQor converters are ideal for customers who need multiple outputs and wish to build or buy point of load converters to work with a 12V rail. RoHS Compliant (see last page).
