SC427MLTRT

Description
The SC417/SC427 is a stand-alone synchronous buck power supply. It features integrated power MOSFETs, a bootstrap switch, and a programmable LDO in a space saving MLPQ-5x5mm 32-pin package.
The device is highly efficient and uses minimal PCB area. It uses pseudo-fixed frequency adaptive on-time operation to provide fast transient response.
Features Input voltage — 3V to 28V Internal power MOSFETs — 10A Integrated bootstrap switch Smart power-save protection Configurable 150mA LDO with bypass capability TC compensated R DS(ON) sensed current limit Pseudo-fixed frequency adaptive on-time control Designed for use with ceramic capacitors Programmable VIN UVLO threshold Independent enable for switcher and LDO Selectable ultra-sonic power-save (SC417) Selectable power-save (SC427) Internal soft-start and soft-shutdown at output Internal reference — 1% tolerance Over-voltage/under-voltage fault protection Power good output Lead-free 5x5mm, 32 Pin MLPQ package Fully WEEE and RoHS compliantApplications Notebook, desktop, tablet, and server computers Networking and telecommunication equipment Printers, DSL, and STB applications Embedded applications Power supply modules Point of load power supplies
