AAT1501/A
REGULATED CHARGE PUMP DC/DC CONVERTERS
Features
General Description
www.DataShzeet4UM.coomnitored Output Voltage
The AAT1501/A is a charge pump DC/DC
(AAT1501: VO = 5V ± 4% )
(AAT1501A: VO = 4.5V ± 4% )
z Output Current: 120mA ( VDD = 3.3V)
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
150mA ( VDD = 3.6V)
z Input Voltage Range: 2.7V to 5.0V
produced by using an internal feedback switched
capacitor voltage doublers.
z A Power-Saving Shutdown Current of less than
The AAT1501/A requires no external inductor
1µA when operating. By using a flying capacitor, the
z Internal Oscillation Frequency : 750kHz
AAT1501/A can deliver up to 120mA ( VDD = 3.3V)
z Compact SOT-23-6 Package
output current for the system. The AAT1501/A’s
typical ultra low operating current, and compact
Pin Configuration
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
VO CF+ power management solution.
