Abstract: An apparatus includes a substrate. A first conductive layer is on the substrate. The first conductive layer includes a first set of conductive segments and a second set of conductive segments. A second conductive layer is over the first conductive layer opposite the substrate. The second metal layer includes a third set of conductive segments and a fourth set of conductive segments. A first set of vias is between the first set of conductive segments and the third set of conductive segments. The first set of conductive segments, the third set of conductive segments, and the first set of vias form a first transformer winding. A second set of vias is between the second set of conductive segments and the fourth set of conductive segments. The second set of conductive segments, the fourth set of conductive segments, and the second set of vias form a second transformer winding.

Abstract: A voltage converter includes a switch network, a rectifier, and a transformer coupled between the switch network and the rectifier. The voltage converter includes an adaptive ON-time generation circuit having a control input and a control output, the control input. The adaptive ON-time generation circuit is configured to receive a WAKE signal to turn ON the switch network, generate a signal indicative of an OFF time of the switch network, and determine an ON time for the switch network based on the signal indicative of the OFF time.
