JW1981 is a single channel Linear LED driver with an integrated 500V MOSFET. The output current is set by an external resistor, adjustable between 5mA and 75mA. It features a patented current control strategy ensuring high output current accuracy, simple system design with few external components, and low BOM cost. It also provides over temperature protection, reducing LED current when the internal chip temperature exceeds 150°C to aid cooling.
