18V, 2A, High Efficiency Synchronous Step-Down Converter CXSD62606 an Adaptive COT control scheme that enables very fast transient response and provides a very smooth transition when the output varies

   产品概述 返回TOPrl8嘉泰姆

        CXSD62606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2A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。CXSD62606采用SOT563封装CXSD62606 is a wide input range, high-efficiency and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 2A 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, CXSD62606 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. CXSD62606 is available in SOT563 package.
