WS9931 Product Description Features  Eliminate ripple current for single stage LED driver  Without external COMP capacitor  Built-in soft-start  Max Output current is up to 300mA  Internal intelligent over temperature protection  Operating temperature range from -40℃to135℃ Applications  LED Tube Lights  LED Bulb Lights LED Ripple Current Elimination Controller Description The WS9931 is an adaptive linear current regulator to eliminate LED low frequency ripple current. It adopts an adaptive control solution without additional circuit design. It can realize the function of LED light non-filtering with very few external components, so the system cost and size are minimized. The WS9931 is mainly applied in bulb lights and tube lights, especially suitable for COB (chip on board) mode.
