一,产品概述(General Description) voltage from a low voltage source. Because of its proprietary design, it starts up at a very low input voltage down to 0.9V, and only consumes 15uA at standby, making it an ideal choice for single cell alkaline/NiMH battery operations.A switching frequency of 1MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count.CXSU6339 is available in SOT23-3 and SOT89-3 Package. 二.产品特点(Features) Efficiency up to 94%@Vin=3.3V, Vout=5.5V Typical 15uA standby current 1MHz Switching Frequency allows small inductor and output cap Input boost-strapping allows using small or no input cap Low Vin Start-up Voltage down to 0.9V Ideal for Single Alkaline Cell operations Maximum Output Current up to 300mA Low Noise PWM control Internally Compensated Current Mode Control Internal Synchronous Rectifier Available in SOT23-3 and SOT89-3 三,应用范围 (Applications) One to Three Cell Battery Operated Devices Medical Instruments Bluetooth Headsets Flash-Based MP3 Players Noise Canceling Headphones 四.技术规格书下载（产品PDF） 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 五,产品封装图 (Package) 七,功能概述
