SC202 Series

Step down Regulator with Integrated Inductor and Digital Programmable Output

Semtech Corporation

The SC202A is a high efficiency 500mA step-down regulator that includes an integrated inductor inside the package.

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.
