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 2uA. Other features of the AIC2322 include high efficiency for all load range, low dropout voltage, short circuit protection, and over temperature protection.
