Abstract:
Based on a control voltage outputted by a secondary-side control circuit and a drain voltage of a second transistor that has a drain electrode connected to a primary winding of a transformer and performs switching operations based on a gate voltage, a control voltage generating circuit of a synchronous rectifier circuit generates the gate voltage of a first transistor. The gate voltage turns off the first transistor irrespective of the control voltage at timing where the drain voltage falls from a first value to a second value.

Claim (Index 1):
A synchronous rectifier circuit comprising:\n a first transistor that has a first terminal, which is connected to a secondary winding of a transformer included in an isolated synchronous rectification-type switching power supply apparatus, and a second terminal, to which a first control voltage is applied, and performs a switching operation based on the first control voltage; a control circuit that detects a first voltage of the first terminal and outputs, based on the first voltage, a second control voltage that controls the switching operation of the first transistor; and a control voltage generating circuit that generates the first control voltage based on the second control voltage and one of a second voltage of a third terminal of a second transistor, which performs a switching operation based on a third control voltage, and a third voltage that changes at a same timing as the second voltage, wherein the third terminal is connected to the primary winding of the transformer and wherein the first control voltage turns the first transistor off irrespective of the second control voltage at timing where the second voltage falls from a first value to a second value.
