High-side FET two-stage adaptive turn-off

In an example, a method includes providing a signal to a driver for a switching voltage regulator to turn off a high-side field effect transistor (FET) of the switching voltage regulator. The method also includes reducing a voltage at a source of the high-side FET. The method includes responsive to...

More Information
Summary:In an example, a method includes providing a signal to a driver for a switching voltage regulator to turn off a high-side field effect transistor (FET) of the switching voltage regulator. The method also includes reducing a voltage at a source of the high-side FET. The method includes responsive to the signal, turning off a pull-down FET coupled to a gate of the high-side FET. The method also includes commutating current from the high-side FET to a low-side FET.
