BCT1473数据手册Broadchip中文资料规格书

描述 Description

The BCT1473 is a high efficiency synchronous buck converter with integrated 90mΩ/50mΩpower MOSFET. The BCT1473 design with anACOT control scheme providing fast transientresponse and supporting both low equivalentseries resistance output capacitors.

The BCT1473 operates in pulse skip mode,which maintains high efficiency during light loadoperation.

The BCT1473 is also equipped withPower-on-reset, soft start, and whole protectionsover-temperature, under-voltage, over-current intoa single package.

This device, available in FCSOT23-6 package,provides a very compact system solution externalcomponents and PCB area.
