TEA1755LT HV start-up DCM/QR flyback controller with integrated DCM/QR PFC controller Rev. 1.1 — 13 March 2015 Product data sheet 1. General description The GreenChip is the latest generation of green Switched Mode Power Supply (SMPS) controller ICs. The TEA1755LT combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration enables cost-effective power supply design using a very low number of external components. The PFC operates in Quasi-Resonant (QR) or Discontinuous Conduction Mode (DCM), with valley switching. The specially built-in green functions provide high efficiency at all power levels. At high power levels the flyback operates in QR mode or DCM with valley detection.
