Use TEA1751 integrated PFC, flyback controller

Posted: 13 May 2009     Print Version  Bookmark and Share

Keywords:TEA1751  PFC  flyback controller 

NXP Semiconductor's TEA1751 is a member of the new generation of PFC and flyback controller combination ICs, used for efficient switched mode power supplies. It has a high level of integration which allows the design of a cost effective power supply with a very low number of external components, says NXP. The TEA1751 is fabricated in a Silicon On Insulator (SOI) process. The NXP claims that its SOI process makes a wide voltage range possible.

The TEA1751 is integrated in to an SO-16 package. Both PFC and flyback controllers operate in quasi resonant/ discontinuous conduction mode with valley detection. The switching is independent for each controller.

This application note describes the functionality and the control functions of TEA1751 and the adjustments needed within the power converter application.
