目录7.相关产品 产品概述 返回TOP The CXSD61059B is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 8A 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 over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. 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 36V n Maximum Duty Cycle 100% n Minimum Drop Out 0.3V n Fixed 180KHz Switching Frequency n 8A Constant Output Current Capability n Internal Optimize Power MOSFET n High efficiency up to 96% n Excellent line and load regulation n Built in thermal shutdown function n Built in current limit function n Built in output short protection function n Built in input over voltage protection n Available in TO220-5L package 应用范围 返回TOP 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
