10A Integrated FET Regulator With Programmable LDO

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 ei cient and uses minimal PCB area. It uses pseudo-i xed frequency adaptive on-time operation to provide fast transient response. The SC417 SC427 supports using standard capacitor types such as electrolytic or special polymer in addition to ceramic, at switching frequencies up to 1MHz. The pro- grammable frequency, synchronous operation, and select- able power-save provide high ei ciency operation over a wide load range. The LDO output is programmable from 0.75V to 5.25V using external resistors. The bias voltage for the device CAN be supplied by the on-chip LDO when VIN > 4.5V, or by an external 5V supply. When a separate source is used as the bias supply, the LDO CAN be programmed to provide a dif erent voltage. By Semtech Corporation
