AC Direct LED driver IC ADT6200 DESCRIPTION The ADT6200 is a AC direct LED driver with very few total components. ADT6200 eliminates the need for the electrolytic capacitor and magnetic components. With superior efficiency, power factor correction and low total harmonic distortion, the ADT6200 is ideal for advanced energy saving LED lighting applications. LED Power is set by only one resistor. ADT6200 ensures high reliability and long life time for LED-based luminaire designs. It also include over-temperature protection, it turns off LED current when its junction temperature exceeds 150℃.
