DESCRIPTION
The JW1769A/B/C is a constant current LED
regulator with high current accuracy which
applies to single stage step-down power factor
corrected LED drivers.600V power MOS is
integrated, which can significantly simplify the
design of LED lighting system.
High accuracy of output current is achieved by
sampling the output current directly. Critical
conduction mode operation reduces the switching
losses and largely increases the efficiency.
JW1769A/B/C is supplied from the output directly,
and auxiliary winding is not needed.
JW1769A/B/C has multi-protection functions
which largely enhance the safety and reliability of
the system, including VCC over-voltage
protection, VCC UVLO, short-circuit protection,
LED open protection, cycle-by-cycle current limit
and over-temperature protection.
