目录7.相关产品 产品概述 返回TOP CXSD62605是一种宽输入范围、高效率和高频DC-DC降压开关稳压器，能够提供高达3A的输出电流。采用COT控制模式，相比PWM控制模式，动态响应显著提升。内置OVP功能保护电路，防止输入电压浪涌。成为液晶电视、机顶盒、便携式电视等工业应用的理想解决方案。CXSD62605采用SOT563封装CXSD62605 is a wide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. It adopts an Adaptive COT control scheme that enables very fast transient response and provides a very smooth transition when the output varies from light load to heavy load. During light load, CXSD62605 goes into a PFM mode that saves switching loss achieving high efficiency. The adaptive COT control also maintains a constant switching frequency across line and load. An OVP function protects the IC itself and its downstream system against input voltage surges. With this OVP function, the IC can stand off input voltage as high as 25V, making it an ideal solution for industrial applications such as LCD TV, Set Top Box, Portable TV, etc. CXSD62605 is available in SOT563 package.产品特点 返回TOP Wide Input Range: 4.5V-18V Adaptive COT Control Ultra-fast load transient response High Efficiency PFM mode at light load High Efficiency Synchronous operation No load IQ 177uA Low Rdson Internal power FETs Capable of Delivering 3A No External Compensation Needed Thermal Shutdown and UVLO Available in SOT563 Package 应用范围 返回TOP LCD TV Set Top Box xDSL Modem 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
