The SC202 is a high efficiency 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 SC202 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 different levels. Pulling all four control pins low disables the output.

The SC202 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.

The SC202 provides several protection features to safeguard the device under stressed conditions. These include short circuit protection, over-temperature protection, under-voltage lockout, and soft start to control in-rush current. These features, coupled with the small 2.5 x 3.0 x 1.0 (mm) package, make the SC202 a versatile product ideal for step-down regulation in products needing high efficiency and a small PCB footprint.
