LNK413LG

The LED driver optimized for flicker-free TRIAC dimming in the table is based on the LNK406EG from the LinkSwitch-PH family of devices.

The minimum output power for the LNK404E/L LED driver is 2.5 W.

The advantages of using the LinkSwitch-PH LED driver include low standby power remote ON/OFF feature (<50 mW at 230 VAC), accurate and consistent performance, compensation for transformer inductance and line input voltage variations, reduced EMI filter size and cost through frequency jittering, advanced protection features such as auto-restart for short-circuit protection and open circuit fault detection mode, automatic thermal shutdown restart with hysteresis, meeting high voltage creepage requirements, being halogen-free and ROHS compliant, and applications in off-line LED drivers. The LinkSwitch-PH also simplifies implementation of LED drivers requiring long lifetime, high efficiency, power factor >0.9, and TRIAC dimming capability. It eliminates the need for a switching stage and electrolytic bulk capacitor, provides accurate constant current control without the need for an optocoupler and current sensing circuits, and offers very wide dimming range, high efficiency, and high power factor. The device integrates the power FET, controller, and start-up functions into a single package, reducing component count and providing high power factor via its internal control algorithm. Continuous conduction mode operation reduces EMI noise, simplifies EMI filtering components, and improves efficiency. The design is fully protected from faults and over temperature.
