SC403MLTRT

Description
The SC403 is a stand-alone synchronous EcoSpeedTM buck power supply which incorporates Semtech’s advanced patent-pending adaptive on-time control architecture to provide excellent light-load efficiency and fast transient response. It features integrated power MOSFETs, a boot strap switch, and a programmable LDO in a 5x5mm package.
The device is highly efficient and uses minimal PCB area.
