Multiple output flyback converter having improved cross-regulation and method of operation thereof |
摘要 |
For use with a flyback converter having a modulator for providing a main switch control signal thereto and main and cross-regulated output circuits, the cross-regulated output circuit subject to ringing and resulting voltage excursion, a voltage excursion controller and a method of operating the same. In one embodiment, the controller includes: (1) a delay circuit, coupled to the modulator, that generates a delay signal based on the main switch control signal and (2) an auxiliary switch, associated with the cross-regulated output circuit, that receives the delay signal and opens to isolate at least a portion of the ringing within said cross-regulated output circuit.
