RDK-193

Reference design kit for a high efficiency (≥81%), high power factor (<gt/>0.9) TRIAC dimmable 7 WTYP LED driver using LinkSwitch®-PH LNK403EG. It includes features such as output open circuit / output short-circuit protected with auto-recovery, line input overvoltage shutdown extends voltage withstand during line faults, auto-recovering thermal shutdown with large hysteresis protects both components and printed circuit board. This high power-factor corrected dimmable LED driver designed to drive 21V at 0.33A from an input voltage range of 90VAC to 265VAC. The LED driver utilizes the LNK403EG from Power Integrations. LinkSwitch-PH ICs allow the implementation of cost effective and low component count LED drivers which both meet power factor and harmonics limits but also offer enhanced end user experience. This includes ultra-wide dimming range, flicker free operation (even with low cost with AC line TRIAC dimmers) and fast, clean turn on.
