COT to EST Converter - Savvy Time
WebIn simple terms, the Constant-On-Time (COT) control scheme depends on a timer circuit (ON-TIMER block) and a voltage comparator (COT Comparator block) to determine the precise timing of the buck switch (high-side MOSFET) and synchronous rectifier (low-side MOSFET) switching as illustrated in WebConstant On-Time (COT) A slight variation to hysteretic control minimizing frequency shift, but with a single voltage-threshold level, yet achieving fast transient response. The on-time is terminated by a one-shot on-timer and is proportional to the input voltage. The off-time is terminated when the feedback voltage falls below the WebJan 2, 2013 · Jan. 2, 2013.
