Semtech SC284A

Dual Channel 2.5MHz, 2.0A Synchronous Buck Regulator

Add to Watch List

The SC284A 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 o$ ers seven pre-determined output voltages via three control pins programmable from 1.0 to 3.3 Volts. The control pins allow for on-the-& y voltage changes, enabling system designers to implement dynamic power savings. The SC284A is also capable of adjusting the output voltage via an external resistor divider.
