Patent ID: 6861826

Claim:
An apparatus for providing switch signaling in a converter system which includes a signal generator, and a high-side transistor switch and a low-side transistor switch implemented as a synchronous rectifier coupled in series at a node, said apparatus comprising: an input for receiving a reference signal from said signal generator, wherein said reference signal is a recurring pulse signal; circuitry coupled to said input and responsive to said reference signal providing a first control signal having a constant pulse width, and providing a second control signal being independent of said high-side transistor switch and having a pulse width modulated on both the trailing and leading edges thereof providing synchronization with said first control signal pulse width, wherein said first control signal is provided to a gate of said high-side transistor switch for activating and deactivating said high-side switch and said second control signal is provided to a gate of said low-side transistor switch for activating and deactivating said low-side switch.
