BCT1477  
3A 600KHz Synchronous Step-Down Converter

GENERAL DESCRIPTION

BCT1477 is a high efficiency synchronous buck converter with integrated 90mΩ/50mΩ power MOSFET. The BCT1477 design with an ACOT control scheme providing fast transient response and supporting both low equivalent series resistance output capacitors.

The BCT1477 operates in pulse skip mode, which maintains high efficiency during light load operation.

The BCT1477 is also equipped with Power-on-reset, soft start, and whole protections over-temperature, under-voltage, over-current into a single package.

This device, available in FCSOT563 package provides a very compact system solution external components and PCB area.
