Abstract

Controlling gate-source voltage with a gate driver in a secondary-side controller in a secondary-controlled converter is described. In one embodiment, an apparatus includes a provider field effect transistor (FET) coupled to a transformer and the secondary-side controller coupled to the transformer. The gate driver is integrated on the secondary-side controller and is configured to control the gate-source voltage and slew rate of the secondary-side FET.
