目录产品概述 返回TOP The CXSU63027 using the external NMOSFET. It is a high efficiency boost converter with 600mV feedback voltage. A switching frequency of 550KHz minimizes solution footprint by allowing the use of tiny low profile inductors and ceramic capacitors. The current mode PWM/PFM design is internally compensated, and the device has a 1.6V startup voltage with 1mA load. It needs few external components, only inductance, resistance and capacitance can meet the driving capacity.产品特点 返回TOP Min1.6V Startup @1mA Load 600mV Feedback Voltage 550KHz Internal Oscillator Soft Startup: 10mS Typical Peak Current Programmable by Bottom Sensing Resistor 300μA Typical Iq Internal PWM/PFM Auto Mode Switching Up to 90% Efficiency External Enable Power OFF Current<1μA Over Voltage Protection 140℃ Thermal Shut Down, 20℃ Hysteresis 应用范围 返回TOP USB Charger 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
