Portable media playersDescrriipttiionThe AP3301-AESA is high efficiencysynchronous, PWM step-down DC/DCconverters working under an input voltage rangeof 2.5V to 5.5V. This feature makes theAP3301-AESA suitable for single Li-lonbattery-powered applications. 100% duty cyclecapability extends battery life in portable devices,while the quiescent current is 200?A with no load,and drops to < 1?A in shutdown.The internal synchronous switch is desired toincrease efficiency without an external Schottkydiode. The 1.4 MHz fixed switching frequencyallows the using of tiny, low profile inductors andceramic capacitors, which minimized overallsolution footprint.The AP3301-AESA converters are available inthe industry standard SOT-23-5 power packages(or upon request). Featturress Up to 95% Efficiency Current Mode Operation for Excellent Lineand Load Transient Response Low Quiescent Current: 200?A Up to 700mA Load Current Soft-start Low Switch on Resistance RDS(ON), InternalSwitch: 0.35? Output Voltage：5.5V～0.6V Automatic PWM/PFM Mode Switching No Schottky Diode Required 1.4MHz Fixed Frequency Switching Short-Circuit Protection Shutdown Quiescent Current: < 1?A Low Profile SOT-23-5 Package (lead-freepackaging is now available)Applliicattiion Digital cameras and MP3 Palmtop computers / PDAs Cellular phones Wireless handsets and DSL modems PC cards
