1. General description
The SSL1750 is a Switched Mode Power Supply (SMPS) controller IC, suitable for driving LED applications from 25 W up to 250 W. For LED power requirements below 25 W the SSL152x family and SSL1623PH are the best choice. The SSL1750 combines a controller for Power Factor Correction (PFC) and a flyback controller. Its high level of integration allows the design of a cost-effective LED power supply with a very low number of external components. The special built-in green functions provide high efficiency at all power levels. This applies to quasi-resonant operation at high power levels, quasi-resonant operation with valley skipping, as well as to reduced frequency operation at lower power levels. At low power levels, the PFC switches over to burst mode control to maintain high efficiency. In burst mode, soft-start and soft-stop functions are added to eliminate audible noise. Duri
