TEA2017ABT/2Y

TEA2017ABT/2Y is a digital configurable LLC and PFC combo controller for high-efficiency resonant power supplies. It includes the LLC controller and a PFC controller that works in DCM/QR mode. The TEA2017ABT enables building a complete resonant power supply which is easy to design and has a very low component count. This 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). Each of these protections can be configured independently and accurately by programming parameters inside the device. The device contains low-voltage and high-voltage silicon technology for high-voltage start-up, integrated drivers, level shifter, protections, and circuitry assuring zero-voltage switching. Applications include desktop and all-in-one PCs, gaming power supplies, LCD television, notebook adapters and general-purpose adapters, printers.
