Each channel offers fifteen predetermined output voltages via separate 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. The SC286 is optimized for maximum efficiency over a wide range of load currents. During full load operation, the device operates in PWM mode with fixed 1.6MHz oscillator frequ...
