Flyback crm
WebTo achieve IEC61000-3-2 Class C regulation requirements, a single-stage flyback converter with PFC is typically used for low power (<25-W) LED lighting applications. Furthermore, among variations of the flyback topology, a primary-side-regulated (PSR) flyback can be the most cost-effective solution. By using a single-stage topology WebTexas Instruments has Flyback controllers to support a wide variety of applications ranging from low power bias to high power density supplies. Our dedicated Flyback controllers …
