Not recommended for new designs.
The SC284P is a dual channel 2A synchronous step-down regulator designed to operate with an input voltage range of 2.75 to 5.5 Volts. Each channel offers seven pre-determined output voltages via three control pins programmable from 1.0 to 3.3 Volts. 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.
