Synchronous rectifying circuit |
摘要 |
A method of efficiently turning off inductive loads includes turning off a driving switch, monitoring a circuit output during turn-off, and activating a control circuit in response to an inductive flyback voltage at the output which turns on a recirculation switch and recirculates residual load current and clamps the output thereby substantially decreasing power dissipation during inductive load turn-off.
