Semtech – SC284P: Dual Channel 2.5MHz, 2.0A Synchronous Buck Regulator with Digital Programmability

The SC284P is a dual channel 2A synchronous step down regulator designed to operate with an input voltage range of 2.75V to 5.5V. Each channel offers seven pre-determined output voltages via three control pins programmable from 1.0V to 3.3V. The control pins allow for on-the-fly voltage changes, enabling system designers to implement dynamic power savings. The SC284P is also capable of adjusting the output voltage via an external resistor divider.
