Description

The AIC1848 charge pump is a micropower charge pump DC/DC converter that produces a regulated output voltage from 2.7V to 4.5V input voltage. Low external-part count (one flying capacitor and two small bypass capacitors) makes the AIC1848 ideal for small, battery-powered applications.

The AIC1848 operates as a constant frequency mode switched capacitor voltage doubler to produce a regulated output and features with thermal shutdown capability and short circuit protection.

The AIC1848 is available in a space-saving SOT-23-6 package.
