Keywords:TEA1751? controller? PFC? flyback? SO-16?

The TEA1751 is a combination controller with a PFC and flyback controller integrated in to an SO-16 package. Both controllers operate in Quasi Resonant (QR) / Discontinuous Conduction Mode (DCM) mode with valley detection. The switching is independent for each controller.

The PFC output power is on-time controlled for simplicity. It is not necessary to sense the phase of the mains voltage. The flyback output power is Current mode controlled for good suppression of input voltage ripple.

The communication circuitry between both controllers is integrated and no adjustment is needed. The voltage and current levels mentioned in this application note are typical values.
