  • Publication number: 20210067026
    Abstract: A synchronous rectifier controller controls a rectification power switch connected in series with a secondary winding between two power lines. The synchronous rectifier has a gate driver and a slew-rate detector. The gate driver drives the rectification power switch. The slew-rate detector detects a channel voltage of the rectification power switch, checks if a slew rate of the channel voltage exceeds a slope threshold. If the slew rate exceeds the slope threshold, the slew-rate detector turns the rectification power switch ON through the gate driver. If the slew rate is less than the slope threshold, the slew-rate detector reduces the slope threshold.
