目录产品概述 返回TOP The CXSD61017 is a 150KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 2.5A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.产品特点 返回TOP n Wide 8V to 40V Input Voltage Range n Output Adjustable from 1.25V to 37V n Minimum Drop Out 0.3V n Fixed 150KHz Switching Frequency n Maximum 3A Switching Current n Internal Optimize Power MOSFET n Excellent line and load regulation n With output constant current loop n Built in thermal shutdown function n Built in current limit function n Built in input over voltage protection n Recommend output power less than 13W n SOP8-EP (Exposed PAD) package 应用范围 返回TOP n Car Charger n Battery Charger n LCD Monitor and LCD TV n Portable instrument power supply n Telecom / Networking Equipment 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
