Abstract
A power supply package for pulse-width modulated control of a power converter includes a first terminal for coupling to a primary winding of a transformer; a second terminal for coupling to an activation gate of an external power switch; a third terminal for coupling to a ground reference; and a fourth terminal for coupling to a combined source of operating power and feedback signal, the feedback signal based on an output load voltage across a secondary winding of the transformer. The package includes an internal power switch having an input coupled to the first terminal, an output coupled to the third terminal, and an activation gate. The package further includes control circuitry responsive to the feedback signal, the control circuitry having a first output coupled to the internal switch activation gate and a second output coupled to the second terminal, the control circuitry configured to drive the internal and external power switches.
