Abstract
A DC to DC converter for controlling the on time and off time of a pair of synchronous switches, which reside in the position of output rectifiers in a half bridge transformer type circuit is provided. The circuit is actually two identical circuits, one for each half of the transformer output. The circuits consist of a voltage reference, a dual comparator, a bias switch, and drive buffer as well as biasing means for proper set up of the various parameters.
