The JW®1758A/B/C/D is a constant current
LED driver with high current accuracy which applies to single
stage high PF buck LED drivers. High voltage power MOS is
integrated, which can significantly simplify the design of LED lighting system.
JW1758A/B/C/D integrates high voltage power
source, and can be supplied by line voltage directly.
High accuracy of output current is achieved
by sampling the output current directly. Critical conduction mode operation
reduces the switching losses and increases the efficiency.
JW1758A/B/C/D has multi-protection functions which largely enhance
the safety and reliability of the system, including VCC over-voltage
protection, VCC UVLO, LED open protection, inductor short protection, pulse-by-
pulse current limit, over-temperature protection.
