TEA1751T HV start-up DCM/QR flyback controller with integrated DCM/QR PFC controller Rev. 3 — 10 January 2013 Product data sheet 1. General description The TEA1751T is the third generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1751T combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective power supply with a very low number of external components. The special built-in green functions provide high efficiency at all power levels. This efficiency applies to quasi-resonant operation at high-power levels, quasi-resonant operation with valley skipping, as well as reduced frequency operation at lower power levels.
