Power FET Circuits

Gate drive method extends supply's input range: 06/26/03  EDN-Design Ideas / Industrial and telecom applications often require a nonisolated, low-voltage supply from a high-voltage input. IC manufacturers have responded to that need with the application of high-voltage processes and offer control ICs that work to 50V and higher. That voltage is sometimes insufficient, and you need further design techniques to extend the input voltage...
