Product Details

The SQ60060QPx55 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 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 48 V to a semi-regulated 12 V or 6 V intermediate bus. SQ 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 or 6 V rail. RoHS Compliant (see page last).
