PMU/tongbu/2019-11-01/459.html target=_blank class=infotextkey>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PMU/tongbu/2019-11-01/459.html target=_blank class=infotextkey>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。PMU/tongbu/2019-11-01/459.html target=_blank class=infotextkey>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。
PMU/tongbu/2019-11-01/459.html target=_blank class=infotextkey>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 PMU/tongbu/2019-11-01/459.html target=_blank class=infotextkey>CXSD6236 also provides more superior load transient response and a seamless transition from PFM to PWM modes. PMU/tongbu/2019-11-01/459.html target=_blank class=infotextkey>CXSD6236 is capable of supplying output with current up to 3.5A at 1.2V output. All these features make EJPMU/tongbu/2019-11-01/459.html target=_blank class=infotextkey>CXSD6236n excellent choice for ARM based CPU power supply.
