DESCRIPTION
The JW1760 is a constant current LED controller
with high current accuracy which applies to single
stage step-down LED drivers.
High accuracy of output current is achieved by
sensing the output current directly. Critical
conduction mode operation reduces the switching
losses and significantly increases the efficiency.
JW1760 can be supplied from the output directly,
and auxiliary winding is not needed.
JW1760 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.
