DESCRIPTION
The AIC2302 is a low-noise, pulse-widthmodulated (PWM), DC-DC step-down converter. The device is available in an adjustable version and fixed output
voltages of 1.0V, 1.2V, 1.8V, and 3.3V. 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 1µA. Other features of the AIC2302 include high efficiency, low dropout
voltage, short circuit protection, over temperature protection, and over
voltage protection. It is available in a small 5 pins SOT23 package.
