- DESCRIPTION
The AIC2304 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 AIC2304 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 and a 6 pins DFN package.
