Abstract
A method for powering driver circuitry for an upper transistor of a half-bridge switching stage includes (1) selectively charging a boot-strap capacitor via a first voltage source such that a voltage at the boot-strap capacitor remains within a predetermined voltage range, (2) clamping the voltage at the boot-strap capacitor to prevent the voltage at the boot-strap capacitor from exceeding a predetermined maximum value, and (3) electrically powering the driver circuitry at least partially via the boot-strap capacitor.
