                                      Description

                                      The SSL8516BT combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration enables cost-effective LED lighting application power supply design using a very low number of external components.

                                      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. At medium power levels, the flyback controller switches to Frequency Reduction (FR) mode and limits the peak current to an adjustable minimum value. In low-power mode, the PFC switches off to maintain high efficiency. At very low power levels, when the flyback switching frequency drops to below 25 kHz, the flyback converter switches to burst mode. During the non-switching phase of the burst mode, the internal IC supply current is minimized to further optimize efficiency. Valley switching is used in all operating modes.

                                      Applications


                                      • Industrial high-bay and low-bay lighting
