GENERAL DESCRIPTION
The AAT1501/A is a charge pump DC/DC converter mainly used for white LED backlighting. It operates with an input voltage ranging from 2.7V to 5.0V to generate constant 5.0V (AAT1501) or 4.5V (AAT1501A) output. The regulated output is produced by using an internal feedback switched capacitor voltage doublers.
