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.
The operating temperature range of the WS9931 is
from -40℃to135℃.
The WS9931 is available in ESOP8 Package.
