Abstract
The synchronous rectifier controller includes a voltage regulator to provide a control voltage to the control terminal of the rectifier switch. The synchronous rectifier controller compares the channel voltage of the rectifier switch with a threshold voltage to generate a comparison result signal. When the channel voltage is greater than the threshold voltage, the comparison result signal has a first logic value, and when the channel voltage is less than the threshold voltage, the comparison result signal has a second logic value. An inverted comparison result signal is generated according to the comparison result signal. When the channel voltage is less than the threshold voltage, the inverted comparison result signal enables a pull-up power supply to pull up the control voltage; and when the channel voltage is greater than the threshold voltage, the comparison result signal enables a pull-down power supply to pull down the control voltage.
