FeaturesUp to 95% Efficiency Current Mode Operation for Excellent Line and Load Transient Response 700mA Output Current Low Quiescent Current: 200μA Output Voltage: 0.6V ～ 5.5V Automatic PWM/PFM Mode Switching No Schottky Diode Required Frequency Operation: 1.0MHz for Fixed Output Voltage and 1.4MHz for Adjustable Output Voltage? Short-Circuit ProtectionShutdown Quiescent Current: <1μALow Profile TSOT/ SOT-23-5L Package (lead-free packaging is now available)Applications Digital cameras and MP3 Palmtop computers / PDAsCellular phonesDescriptionThe AP3301 is high efficiency synchronous, PWM step-down DC/DC converters working under an input voltage range from 2.2V to 5.5V. This feature makes the AP3301 suitable for single Li-Lon battery-powered applications. 100% duty cycle capability extends battery life in portable devices, while the quiescent current is 200μA with no load, and drops to <1μA in shutdown. The internal synchronous switch is desired to increase efficiency without an external Schottky diode. The 1.0MHz/1.4MHz switching frequency allows the using of tiny, low profile inductors and ceramic capacitors, which minimized overall solution footprint. The AP3301 converters are available in the industry standard TSOT/SOT-23-5L power packages (or upon request). Wireless handsets and DSL modems Portable media playersPC cards
