SC195 500mA Synchronous Step Down DC-DC Regulator

The SC195 is a high efficiency, 500mA step down regulator designed to operate with an input voltage range of 2.9V to 5.5 V. Four control logic pins are used to select the output voltage, eliminating the need for external feedback resistors. The control pins allow the output voltage to be set to a single level or controlled dynamically. Fifteen different outp.

Four control logic pins are used to select the output voltage, eliminating the need for external feedback resistors. The control pins allow the output voltage to be set to a single level or controlled dynamically. Fifteen different output voltages can be selected. Pulling all four control pins low disables the output. The SC195 operates at a fixed 3.5MHz switching frequency, minimizing the size and cost of external comp.
