Abstract
A regulated power supply includes a capacitively isolated feedback circuit and a pulse width modulator (PWM) operable to produce a plurality of pulses at an output and receive a sampled voltage at a feedback input thereof. The capacitively isolated feedback circuit includes a capacitively isolated gate drive circuit directly coupled to the PWM output and configured to produce a plurality of isolated pulses from the plurality of pulses received from the PWM output. The capacitively isolated feedback circuit also includes a forward converter feedback circuit, which includes a switching transistor directly coupled to the capacitively isolated gate drive circuit for receiving the plurality of isolated pulses at a gate of the switching transistor and a feedback transformer directly coupled to the PWM for providing the sampled voltage at the feedback input. The plurality of isolated pulses causes the feedback transformer to sample a load voltage as the sampled voltage.
