Abstract
A voltage conversion circuit is responsive to a pulse-width modulated control signal for alternately enabling the gates of first and second field effect transistors which converts a high voltage input signal to a low voltage output signal. A first state of the control signal passes the high voltage input signal through the first transistor to charge a filter, while a second state of the control signal blocks the high voltage input signal from the filter. The second state of the control signal also sources current through the second transistor to the filter to rectify the low voltage output signal. The first and second transistors have non-overlapping conduction periods.
