2A 550K/1.1MHz Synchronous PWM Step-Down Converter

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 th • 2.5V to 6V Input Voltage Range\n• Adjustable Output Voltage from 0.8V to Vin\n• 2.0A Guaranteed Output Current\n• 94% Efficiency at Heavy Load(Vin=5V, Vout=3.3V, Iout=2.0A)\n• Low RDS(ON) Internal Switches: 110mOhm\n• No Schottky Diode Required\n• 100% Duty Cycle in Low Dropout Operation\n;
