General Description
WS3110 is a power factor correctionprimary-side-control
LED lighting driver with advanced features to provide high
efficiency control for lighting application.
WS3110 applies source driver technologyits internal fast
start-up circuit greatly shorten the start-up time while
keeping extremely low standby power consumption.
With internal line-compensation, the WS3110 provides
accurate constant current (CC ± 5%) regulation at
universal AC input.
WS3110 offers complete protection coverage with
automatic self-recovery feature including cycle by cycle
over current protection (OCP), VCC over-voltage
protection (VCC-OVP) and under voltage lockout (UVLO),
output LED short/open protection, CS pin short/open
protection, and over-temperature protection (OTP). The
gate-driven output ST is clamped to maximum 15V to
protect the external MOSFET. Excellent EMI performance
is achieved by using soft-driver technology.
WS3110 is offered in SOP-8 packages.
