SSL8516T:Flyback power supply controller IC with PFC for LED lighting

The SSL8516T 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. It ensures high efficiency while minimizing the audible noise from the transformer. In low power mode, the PFC switches off to maintain high efficiency. Valley switching is used in all operating modes.
