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.
