ABSTRACT:
For use with a power supply having a controllable switch that switches in response to a drive signal received from a drive signal generator, a circuit for, and method of, modifying the drive signal to cause the switch to turn on at a reduced voltage. The circuit includes: (1) a synchronization signal generating circuit that senses an electrical characteristic of the supply representing a voltage across the switch, the synchronization signal generating circuit developing a synchronization signal as a function of the characteristic and (2) a drive signal modifier circuit that receives the synchronization signal and causes the drive signal generator to modify the drive signal in response thereto, the synchronization signal generating circuit and drive signal generator cooperating to synchronize the drive signal to the characteristic thereby to reduce power dissipation in the switch.
