Not recommended for new designs.
The SC284AQ is a dual channel 1.7A synchronous stepdown 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 SC284AQ is also capable of adjusting the output voltage via an external resistor divider.
