Abstract:
A synchronous power converter controlling simultaneous non-conductive states of first and second transistors, comprising:a first delay control circuit coupled to receive the first timing signal and coupled to minimize a first simultaneous conductive state; a second delay control circuit coupled to receive the second timing signal and coupled to minimize a second simultaneous conductive state; and a charge control circuit coupled to receive first and second control signals indicative of first and second conduction states of the first and second transistors and coupled to provide first and second timing signals, wherein the charge control circuit comprises a first current mirror coupled to receive the first control signal and coupled to provide a first phase of the first timing signal at a first node, a second current mirror coupled to receive the second control signal and coupled to provide a first phase of the second timing signal at a second node, a first current definition device coupled to the first node to provide a second phase of the first timing signal, and a second current definition device coupled to the second node to provide a second phase of the second timing signal.
