Description
This is a high efficiency 65W AC/DC design for a Universal input (85Vac to 265Vac) to 19.5V @3.33A output exceeding CoC-5 Tier2 and DOE Level VI requirements for external power supplies using the LM5023 Quasi-Resontant Flyback Controller with UCC24630 Synchronous Rectification Controller and CSD19531Q5A MOSFET. Additionally the LM8364 reset controller is used to provide input line AC UVLO protection.
