Abstract
Various embodiments provide a resonant converter that includes a synchronous rectifier driver. The synchronous rectifier driver reduces voltage spikes on drains of transistors within the resonant converter by placing an active clamp between the drains of the transistors and an output terminal of the resonant converter. The active clamp reduces the voltage spikes by sinking current at the drains of the transistors to an output capacitor. By sinking the current to the output terminal, power loss is minimized and efficiency of the resonant converter is improved.
