NXP Semiconductors TEA2017

The TEA2017AAT is a digital configurable LLC and PFC combo controller for high efficiency resonant power supplies. It includes both the LLC controller and PFC controller functionality.

The PFC can be configured to operate in DCM/QR, CCM fixed frequency, or multimode which supports all operation modes to optimize the PFC efficiency.

The TEA2017AAT enables building a complete resonant power supply which is easy to design and has a very low component count.

Key features

• Digital configurable LLC & PFC combo controller
• Integrated high-voltage start-up
• Integrated drivers and high-voltage level shifter (LS)
• High-side driver directly supplied from the low-side driver output

Additional 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
• Several parameters can easily be configured during evaluation with use of the graphical user interface (GUI), like:
  • Operating frequencies to be outside the audible area at all operating modes
  • Soft start and soft stop in burst mode, reducing the audible noise
  • Accurate transition levels between operation modes (high-power mode/low-power mode/burst mode)
  • Enabling/disabling the lower power mode

Applications

• Adapters
• Power supplies for desktop PC and all-in-one PC
• Power supplies for gaming consoles
• Power supplies for UHD LED / OLED television
• Power supplies for servers / 5G
