一.产品概述

   CXSD6236是一款全新的，结合电压模式控制和固定开启时间（COT）优点的高频同步降压转换器。其自适应的COT控制方式，可以在使得最快的负载瞬态响应的同时，确保振荡频率基本维持不变。同时CXSD6236实现了在极低的输出电压（极低占空比）下控制环路在高速响应负载变化的前提下保持稳定，并实现轻载PFM和重载PWM控制模式下的平稳过渡。CXSD6236可在1.2V输出下提供超过3.5A的电流，是为智能产品的主控供电的最佳选择。 

   CXSD6236 belongs to a new breed of high frequency synchronous Step-Down converters that combines the advantages of voltage mode control and Constant-On-Time control. Its adaptive Constant-On-Time control dynamically changes switch on time to achieve a constant switching frequency. It does not have the minimum on-time constrain normally a fixed-frequency current mode Step-down requires, allowing it to go down to very low duty ratio without affecting loop stability. The voltage mode nature of CXSD6236 also provides more superior load transient response and a seamless transition from PFM to PWM modes. CXSD6236 is capable of supplying output with current up to 3.5A at 1.2V output. All these features make EJCXSD6236n excellent choice for ARM based CPU power supply.
