Advanced Analog Technology AAT1501

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.

GENERAL DESCRIPTION

Output Voltage (AAT1501: VO = 5V ± 4% ) (AAT1501A: VO = 4.5V ± 4% ) z Output Current: 120mA ( VDD = 3.3V) 150mA ( VDD = 3.6V) z z z z Input Voltage Range: 2.7V to 5.0V A Power-Saving Shutdown Current of less than 1µA The AAT1501/A requires no external inductor when operating. By using a flying capacitor, the AAT1501/A can deliver up to 120mA ( VDD = 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.
