RC4191 Datasheet Micropower Switching Regulator

Manufacturer: Fairchild (now onsemi)

Overview: www.fairchildsemi.com RC4191/RC4192/RC4193 Micropower Switching.

General Description

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 detection circuit.
