3.2A 550k/1.1MHz Synchronous PWM
FEATURES
2.5V to 6V Input Voltage Range
Adjustable Output Voltage from 0.8V to Vin
3.2A Guaranteed Output Current
Up to 95% Efficiency
Low RDS(ON) Internal Switches: 110mΩ
No Schottky Diode Required
100% Duty Cycle in Low Dropout Operation
Fixed 550k/1.1MHz Operating Frequency

Step-Down Converter
DESCRIPTION
The AIC2323 is a low-noise, pulse-width-
modulated (PWM), DC-DC step-down converter.
The device features an internal synchronous
rectifier for high efficiency; it requires no external
Schottky diode. Shutdown mode places the
device in standby, reducing supply current to
under 2µA. Other features of the AIC2323
include high efficiency for all load range, low
dropout voltage, short circuit protection, and
over temperature protection.
