Abstract
In an embodiment, a power switch controller for driving a back-to-back power switch includes: an amplifier having a supply terminal configured to receive a supply voltage, an output configured to be coupled to a gate terminal of the back-to-back power switch, a first input configured to be coupled a source terminal of the back-to-back power switch, and a second input coupled to the output of the amplifier. The amplifier is configured to generate an output voltage at the output of the amplifier, the output voltage being an offset voltage higher than a voltage at the first input of the amplifier.
