Zusammenfassung:A power converter system includes first and second input terminals; a converter connected to the first and second input terminals and including an output terminal; a start-up circuit connected to a first capacitor and configured to charge the first capacitor during start-up and hiccup conditions; a voltage source connected to the first and second input terminals and configured to provide, during the start-up and hiccup conditions, a voltage proportional to a voltage applied to the first and second input terminals; and a voltage buffer including a MOSFET with a gate connected to the voltage source, a source connected to the start-up circuit, and a drain connected to one of the first and second input terminals.
