Abstract
A high-side driver circuit for a switching power supply, configured to translate a low-side switching control signal referenced to a first ground rail to a high-side switching control signal referenced to a second, high-side ground rail for driving a switching control connection of a power switching device, the high-side driver circuit including first and second inputs to receive first and second low-side switching control signals; a differential amplifier having a differential pair of inputs coupled to said first and second inputs and having an output, the differential amplifier having a ground connection for connection to said high-side ground rail and a power connection to receive a power supply from a second voltage supply; and an output coupled to said differential amplifier output to provide the high-side switching control signal.
