The timing controller has a ramp generator providing a ramp signal at a first capacitor. The ramp signal corresponds to a discharge time when the body diode is forward biased. A second capacitor records an estimated duration signal. An update circuit is connected between the first and second capacitors, for shorting the first and second capacitor to update the estimated duration signal by charge sharing. A comparator with two inputs coupled to the ramp signal and the estimated duration signal respectively compares the ramp signal and the estimated duration signal to control the synchronous rectifier."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Timing control method and apparatus for synchronous rectifier using estimated duration signal","description":"A timing controller provides adaptive timings to control a synchronous rectifier with a body diode.
