Output Current: 120mA ( V_DD = 3.3V)
150mA ( V_DD = 3.6V)
Input Voltage Range: 2.7V to 5.0V
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.
