ABSTRACT:
A method of providing threshold voltage monitoring and control in synchronous power converters is disclosed. The method establishes a threshold voltage level for at least one of an upper gate and a lower gate power switch in a synchronous power converter. The threshold voltage levels indicate switching delay times are present in the upper and lower gate power switches. The method detects body diode conduction levels for both the upper and lower gate power switches. When at least one of the detected body diode conduction levels exceed a prescribed body diode conduction level, the method adjusts the threshold voltage level for at least one of the upper and lower gate power switches to reduce a body diode conduction time for the at least one of the upper and lower gate power switches.
