目录7.相关产品 产品概述 返回TOP CXSU63272 is a high efficiency synchronous step-up converter with ultra- low quiescent current down to 1uA. It is capable of delivering at least 2W of power from a low voltage source, i.e. 0.4A at 5V output. It also features a true-shutofffunction that disconnects the input from output, during shutdown and output short-circuit conditions. This eliminates the need for an external MOSFET and its control circuitry to disconnect the input from output and provides robust output overload protection. A switching frequency of 1.4MHz minimizes solution footprint by allowing the use of tiny and low profile inductors and ceramic capacitors. An intemal synchronous MOSFET provides highest efficiency and with a current mode control that is internally compensated, external parts count is reduced to minimal. With the ultra-low IQ feature, CXSU63272 is ideal for solution that requires low standby power and compact board size such as loT applications. CXSU63272 is housed in a SOT23-6 and DFN2x2-6 package产品特点 返回TOP Ultra low IQ when No Switching :1uA Qutput Disconnect Short-circuit Protection 5V/0.4A Qutput Power Qutput to Input Reversed Current Protection Up to 94% Efficiency Internal Synchronous Rectifier Current IVlode control Logic Control Shutdown and Thermal shutdown SQT23-6&DFN2X2-6 Package 应用范围 返回TOP Tablet, MID ♦ Smart Phone ♦ Power Bank 技术规格书（产品PDF) 返回TOP 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！ 产品封装图 返回TOP
