WS3110 is a power factor correction,primary-side-control LED lighting driver with advanced features to provide high efficiency control for lighting application.
WS3110 applies source driver technology,its 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.
