A resonant gate drive for an externally-driven synchronous rectifier circuit (18). The circuit (18) comprises a first and second first synchronous rectifier recovery switch (SQ3, SQ46), and a first and second sychronous rectifier recovery switch (SQ5, SQ6), and an at least one inductor (LR). The at least one inductor (LR) stores the energy from the capacitance of the first and second synchronous rectifiers (SQ1, SQ2) upon charging or discharging of the first and second synchronous rectifiers (SQ1, SQ2). The recovery switches (SQ3, SQ4, SQ5, SQ6) transfer the stored energy from the at least one inductor (LR) to the output terminal (22) creating a more energy efficient circuit. |
