Abstract
Push-pull circuits are described that are suitable for the driving of LEDs and that reduce the voltage stress on the switching transistors that is caused by the output transformer. The push-pull arrangement caters to reducing the size of the transformer as it eliminates the DC magnetic bias of the transformer core and it also caters to the integration of the semiconductor content of the circuit requiring only low side DMOS to be implemented in the monolithic, junction isolated process.
