JW®19818C is a single channel linear LED driver with 500V MOSFET integrated, and the output current is set by the external resistor. Patented current control strategy ensures high output current accuracy while the system is simple with few external components and very low BOM cost. JW19818C provides over temperature protection. When temperature inside chip exceeds OTPCHIP, JW19818C deceases LED current, which can help chip cooling.
