Parameters Subject to Change Without Notice JW1806M/JW1806A JW1806B/JW1806C TRIAC Dimmable Boost LED Driver DESCRIPTION JW®1806M/ JW1806A/ JW1806B/ JW1806C (JW1806X series) is an offline LED driver suitable for TRIAC dimming, which supports boost topology. JW1806A series achieves good line and load regulation by a close-loop current regulator integrated. Patented current sensing and digital compensation technics ensure a unit power factor and high accuracy output current. The critical conduction mode operation reduces the switching loss and increases the efficiency. JW1806X series is supplied from line voltage directly, eliminating auxiliary winding and start-up circuitry, which can lower the system BOM cost. Excellent algorithms ensure good dimmer compatibility.
