TEA2017AAT/3Y

TEA2017AAT/3Y is a digital configurable LLC and multimode PFC controller. 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. The TEA2017AAT enables building a complete resonant power supply which is easy to design and has a very low component count. The TEA2017AAT digital architecture is based on a high-speed configurable hardware state machine ensuring very reliable real-time performance. The TEA2017AAT contains all protections like overtemperature protection (OTP), overcurrent protection (OCP), overvoltage protection (OVP), overpower protection (OPP), open-loop protection (OLP), and capacitive mode regulation (CMR). Applications include desktop and all-in-one PCs, gaming power supplies, LCD television, notebook adapters and general-purpose adapters, printers, server, 5G supplies, UHD LED television.
