Description

The AIC1845 is a micropower charge pump DC/DC converter that produces a regulated 5V output. The input voltage range is 2.7V to 5.0V. Extremely low operating current (13uA typical with no load) and a low external-part count (one 0.22uF flying capacitor and two small bypass capacitors at VIN and VOUT ) make the AIC1845 ideally suitable for small, battery-powered ap-plications.

The AIC1845 operates as a PSM (Pulse Skip-ping Modulation) mode switched capacitor volt-age doubler to produce a regulated output and features with thermal shutdown capability and short circuit protection.

The AIC1845 is available in a 6-pin SOT-23 package.
