Product Details

The SQ60120QPA28 bus converter is a next-generation, board-mountable, isolated, fixed switching frequency dcdc converter that uses synchronous rectification to achieve extremely high conversion efficiency. The SQ BusQor® series provides an isolated step down voltage from 48 V to a semi-regulated 12 V 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 12 V rail. RoHS Compliant (see last page).
