Overview
AIC2322 2A 550k/1.
1MHz Synchronous PWM  FEATURES  2.
5V to 6V Input Voltage Range  Adjustable Output Voltage from 0.
8V to Vin  2.
0A Guaranteed Output Current  94% Efficiency at Heavy Load (Vin=5V, Vout=3.
3V, Iout=2.
0A)  Low RDS(ON) Internal Switches: 110mΩ  No Schottky Diode Required  100% Duty Cycle in Low Dropout Operation  Fixed 550k/1.
1MHz Operating Frequency  Optional Soft-Start Internal Fixed 1ms Soft- Start Step-Down Converter  DESCRIPTION The AIC2322 is a low-noise, pulse-widthmodulated (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 AIC2322 include high efficiency for all load range, low dropout voltage, short circuit protection, and over temperature protection.
 APPLICATIONS  LCD TV  Multi-function Peripheral  Cellular Phones  CPU I/O Supplies  PDAs and Handy-Terminals  Battery-Operated Devices (1 Li-Ion or 3 NiMH/ NiCd).
