Product Description

The SC202A input voltage range makes it ideal for battery operated applications with space limitations. The output voltage can be fixed to a single setting or dynamically switched between different levels. Pulling all four control pins low disables the output. The SC202A operates at a fixed 3.5MHz switching frequency in normal PWM (Pulse-Width Modulation) mode. A variable frequency PSAVE (power-save) mode is used to optimize efficiency at light loads for each output setting. Built-in hysteresis prevents chattering between the two modes.
