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.

The AAT1501/A requires no external inductor

when operating. By using a flying capacitor, the

AAT1501/A can deliver up to 120mA (

DD

V

= 3.3V)

output current for the system. The AAT1501/A’s

typical ultra low operating current, and compact

external parts make it an ideal component for small,

portable, battery-powered applications.

AAT1501/A comes in a compact 6-pin SOT-23

package to offer users optimal and economical

power management solution.
