SC283 POWER MANAGEMENT Features                    Dual Channel 2.5MHz, 1.8A Synchronous Step-Down Regulator Description The SC283 is a dual channel 1.8A synchronous stepdown regulator designed to operate with an input voltage range of 2.9 to 5.5 Volts. Each channel offers fifteen pre-determined output voltages via four control pins programmable from 0.8 to 3.3 Volts. The control pins allow for on-the-fly voltage changes, enabling system designers to implement dynamic power savings. The SC283 is also capable of adjusting the output voltage via an external resistor divider. The device operates with a fixed 2.5MHz oscillator frequency, allowing the use of small surface mount external components.
