The SSL8516T combines a controller for Power Factor Correction (PFC)and a flyback controller. Its high level of integration enables cost-effective LED lightingapplication 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 highpower levels, the flyback operates in QR mode or DCM with valley detection. At mediumpower levels, the flyback controller switches to Frequency Reduction (FR) mode and limitsthe peak current to an adjustable minimum value. It ensures high efficiency whileminimizing the audible noise from the transformer. In low power mode, the PFC switchesoff to maintain high efficiency. Valley switching is used in all operating modes.
