High Efficiency Adaptive Charge pump 5V Boost

General Description

The FAN5665 is a 5V switched capacitor step-up DC/DC converter with an input voltage range from 2.9V to 5.5V. Switch reconfiguration and fractional switching techniques are utilized to achieve high efficiency over the entire input voltage range. The FAN5665 includes built-in under-voltage lockout, short circuit, and thermal protection circuitry. The FAN5665 is available in an 8-bump 0.4mm pitch WLCSP package.
