Abstract
A circuit having a first circuit portion configured to receive a pulse-width modulated first signal and a second signal, and configured to generate third and fourth signals each responsive to the first and second signals; a second circuit portion configured to receive the third and fourth signals and to generate a fifth signal responsive to both the third and fourth signals; and a third circuit portion configured to control an on/off state of a first switch in response to the fifth signal, wherein the second signal is present at a load path terminal of the first switch. Also, various related methods.
