SC183CULTRT

The SC183C is a 2A synchronous step-down regulator designed to operate with an input voltage range of 2.9 to 5.5 Volts. The device offers fifteen pre-determined outputs 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 SC183C is also capable of adjusting 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.Connecting CTL0 — CTL3 to logic low forces the device into shutdown mode reducing the supply current to less than 1µA.The SC183C is available in a thermally-enhanced, 3mm x 3mm x 0.6mm MLPQ-UT16 package.
