目录7.相关产品 产品概述 返回TOP The CXSD62376 is a high efficiency, 2A buck converter with two low RDS(ON) switches. It operates from 5V to 14V input voltage range, and provides up to 2A continuous output current with the output voltage adjustable down to 0.8V. Whenever the load is light, the CXSD62376 automatically change the PWM operation mode to PFM operation to minimize the power consumption. Hence it is suitable for battery-powered devices. The CXSD62376 is available in a SOP-8 package.产品特点 返回TOP „ 5V to 14V Input Supply Range „ Up to 95% Efficiency „ Synchronous Switches „ No External Schottky Diodes Needed „ Internal Soft Start „ Output Voltage Adjustable to 0.8V „ 2A continuous output current „ Fixed 500kHz Switching Frequency „ PWM/PFM Operations „ Cycle-by-Cycle Current Limit „ Short Circuit Protection „ Thermal shutdown „ SOP-8 Package 应用范围 返回TOP „ Note Book Computers „ Portable DVD players „ Optical Storages „ LCD Panels „ Telecom Equipments „ Portable Devices 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
