DESCRIPTION
The AIC2322 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 AIC2322
include high efficiency for all load range, low
dropout voltage, short circuit protection, and
over temperature protection.
