Description
WS3240 is a high precision primary side feedback
constant current LED driver, suitable for flyback isolated
LED in sub 4W power range at universal AC input. It
operates in discontinuous current mode.
WS3240 integrates 650V power MOS. It operates in
primary side sensing and regulation, without a secondary
feedback circuit, also need not the auxiliary transformer
winding detection and power supply, only need few
peripheral components can realize constant current,
greatly saves the cost and size of the system.
The start time of WS3240 is less than 100ms at
universal AC input with the high voltage start technology,
realizing instant bright of the LED lamp.
The current precision is less than ± 5%
with high precision current sampling circuit and line
compensation. With patented constant current controlling
mode, excellent linear regulation is achieved.
WS3240 provides a variety of comprehensive
protection mode, including: cycle by cycle current limit
protection(OCP), LED open/short circuit protection, under
voltage protection and clamping, over temperature
protection, pin floating protection etc..
WS3240 is offered in TO-92 package.
