TEA2017AAT
Description
The TEA2017AAT is a digital configurable LLC and PFC combo controller for highefficiency resonant power supplies. It includes the LLC controller and PFC controller functionality.
Key Features
- Complete functionality of a PFC and LLC controller in a single small-size SO16 package
- Integrated high-voltage start-up
- Integrated drivers and high-voltage level shifter (LS)
- High-side driver directly supplied from the low-side driver output
- Accurate boost voltage regulation
- PFC can be configured to operate in: - DCM/QR - DCM/QR/CCM (also called multimode operation) - CCM fixed frequency
- Integrated X-capacitor discharge without additional external components
- Power good function
- PFC jitter for optimized EMI performance
- Excellent power factor (PF) and total harmonic distortion (THD), as the PFC current compensates for the input filter current
