ABSTRACT:
A switching boost regulator, including auxiliary circuitry having an auxiliary switch and inductor connected to operate the regulator in a zero-voltage transition mode, achieves substantial efficiency improvement by limiting losses in the auxiliary circuitry dedicated to achieving zero-voltage transition operation. Loss reduction circuitry included with the auxiliary circuitry cooperatively operates to limit turn-on and conduction losses and to suppress ringing of the components of the auxiliary circuit.
