JWB1981 Parameters Subject to Change Without Notice Single-Channel Linear LED Driver DESCRIPTION JW®B1981 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. JWB1981 provides over temperature protection. When temperature inside chip exceeds OTPCHIP, JWB1981 deceases LED current, which can help chip cooling.
