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 ponents 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. pany’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of JoulWatt technology Inc.
