BQ55090QEx60数据手册Synqor中文资料规格书

描述 Description

The BusQor BQ55090QEx60 bus converter is a nextgeneration, 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 48 V to 12 or 9.6 V intermediate bus with no regulation in a standard quarter-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.
