ABSTRACT:
This circuit converts a DC voltage of one value to a regulated DC voltage of another value. The circuitry includes a variable frequency clock controlled by an error voltage derived from the converter output. A pulse of constant length is produced for each cycle of the clock. Logic circuitry is arranged to alternately feed these constant length pulses to opposite sides of a push-pull power amplifier, the output of which is rectified and filtered to form the converter output.
