Description
The WS9841 is a high efficiency TRIAC dimmable LED driver. The device operates in critical conduction mode and is suitable for buck, buck-boost or fly-back LED lighting.
The WS9841 integrates a 300V power MOSFET. It utilizes patent pending MOSFET driving technique and current sensing method. The operating current of the IC is very low. With very few external components count, it can achieve excellent constant current performance, so the system cost and size are greatly reduced.
The WS9841 offers rich protection functions to improve the system reliability, including LED open circuit protection,LED short circuit protection, VCC under voltage protection,CS resistor short circuit protection and thermal regulation function.
The WS9841 is available in a SOP-8 Package.
