Abstract
An apparatus comprises: a voltage converter, a first switch, a second switch, and a controller. The voltage converter includes a combination of a primary winding and an auxiliary primary winding magnetically coupled to a secondary winding. The auxiliary primary winding is operable to generate a feedback voltage signal. The secondary winding is operable to receive energy from the primary winding to produce an output voltage to power a load. The controller controls switching operation of the first switch and the second switch to control a flow of current through the primary winding. The controller is further operable to: i) via a feedback voltage signal from the auxiliary primary winding, monitor a flow of current through a body diode of the second switch, and ii) control subsequent activation of the first switch to an ON state based on the monitored flow of current through the body diode of the second switch.
