TEA2017AAT/2Y

TEA2017AAT is a digital configurable LLC and multimode PFC controller for high efficiency resonant power supplies. It includes 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. This enables building a complete resonant power supply which is easy to design and has a very low component count. Its digital architecture is based on a high-speed configurable hardware state machine ensuring very reliable real-time performance. The configurations can be fully secured to prevent unauthorized copying of the proprietary TEA2017AAT configuration content. Typical applications are desktop and all-in-one PCs, gaming power supplies, LCD television, notebook adapters and general-purpose adapters, printers, server, 5G supplies, UHD LED television.

• 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
• PFC can be configured to operate in: DCM/QR, DCM/QR/CCM (multimode operation), CCM fixed frequency
• Integrated X-capacitor discharge without additional external components, power good function
• PFC jitter for optimized EMI performance, accurate boost voltage regulation
• Excellent power factor (PF) and total harmonic distortion (THD)
• Several parameters can easily be configured during evaluation by using graphical user interface
• Operating frequencies to be outside the audible area at all operating modes
• Soft start and soft stop in burst mode, reducing the audible noise
