The SC202F is a high effi ciency 500mA step-down regulator that includes an integrated inductor inside the package. The input voltage range makes it ideal for battery operated applications with space limitations. The SC202F operates at a fi xed 3.5MHz switching frequency in normal PWM (Pulse-Width Modulation) mode. The SC202F also includes fifteen programmable output voltage settings that can be selected using the four control pins, eliminating the need for external feedback resistors. The output voltage can be fixed to a single setting or dynamically switched between diff erent levels. Pulling all four control pins low disables the output.
