SC187
The SC187 is a 4A synchronous step-down regulator designed to operate with an input voltage range of 2.9V to 5.5V. The device 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 device is also capable of adjusting output voltage via an external resistor divider.
