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.
