RC4193 - Fairchild Semiconductor

RC4193 (RC4191 - RC4193) Micropower Switching Regulator

The RC4191/4192/4193 series of monolithic ICs are low power switch mode regulators intended for miniature power supply applications. These DC-to-DC converter ICs provide all of the active components needed to create supplies for micropower circuits. Contained internally are an oscillator, switch, reference, comparator, and logic, plus a discharged battery de.
