The input voltage range makes it ideal for battery operated applications with space limitations. The SC195B 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 c...
