Abstract

In one form, a synchronous rectifier controller includes a drive clamp adjust terminal, a drive terminal, a clamp voltage generator circuit coupled to the drive clamp adjust terminal for measuring a signal at the drive clamp adjust terminal and providing a clamp voltage having a value determined by the signal, and a driver for providing a drive signal to the drive terminal at a voltage related to the clamp voltage during an active period of the drive signal. In an alternate form a power converter includes a rectifier transistor having a first current electrode, a control electrode for receiving a drive signal, and a second current electrode, and a synchronous rectifier controller having a first terminal coupled to the control electrode of the rectifier transistor for providing the drive signal alternately in an active state and an inactive state.
