BCT1473
3A 600KHz Synchronous Step-Down Converter
GENERAL DESCRIPTION
The BCT1473 is a high efficiency synchronous buck converter with integrated 90mΩ/50mΩ power MOSFET. The BCT1473 design with an ACOT control scheme providing fast transient response and supporting both low equivalent series resistance output capacitors.
The BCT1473 operates in pulse skip mode, which maintains high efficiency during light load operation.
The BCT1473 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 FCSOT23-6 package, provides a very compact system solution external components and PCB area.
