SC195F
Not Recommended for New Designs
The SC195F is a high efficiency, 500mA step down regulator designed to operate with an input voltage range of 2.9V to 5.5 V. The input voltage range makes it ideal for battery operated applications with space limitations. The SC195F operates at a fixed 3.5MHz switching frequency in normal PWM (Pulse-Width Modulation) mode. The SC195F 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.
