SC190 Datasheet (Semtech) - Synchronous Buck Converter

SC190, Synchronous Buck Converter

The SC190 is a synchronous step-down converter with integrated power devices and an integrated front-end LDO to minimize input supply ripple.

Output voltage is programmable using two control bits, eliminating the need for feedback resistors tied to the output.

The device is offered in four distinct
