Abstract
According to an embodiment of the invention, an apparatus includes a microprocessor-based pulse-width modulation controller configured to generate a pulse-width modulation signal, and a synchronous converter including a first transistor, a second transistor, a first driver, and a second driver. The apparatus further includes a drive voltage generator configured to generate a drive voltage for the synchronous converter. The drive voltage generator is further configured to generate the drive voltage based on a measured output current and a measured input voltage.
