Description
The TEA2017DB1580 is a 240 W demo board built around the TEA2017, which includes both the PFC and LLC controller.The PFC can be configured to operate in DCM/QR, fixed frequency or multimode (DCM/QR/CCM). The input current is shaped such that an optimum THD/PF is reached. The no-load power consumption is below 100 mW and the efficiency can meet the efficiency regulations of Energy Star, the Department of Energy (DoE), the Ecodesign Directive of the European Union, the European Code of Conduct and other guidelines. The board is on-the-fly digital configurable, which means that the properties of the TEA2017 can be adapted while the circuit is working.
Features
- Output 12 V/20 A
- Input voltage range 90 V-264 V
- DCM/QR/CCM fixed frequency mode PFC controller
- Excellent PF and THD performance
- Integrated X-capacitor discharge without additional external components
- Well-powered function
- Digital configurable
- Synchronous rectifier at secondary side
Typical applications
- LCD television, Desktop and all-in-one PCs, UHD LED television
- Gaming power supplies, 5G supplies, Notebook adapters and general-purpose adapters
- Server
