Offline Step-down LED Controller
With PFC and No Auxiliary Winding
The JW®1765 is a constant current LED controller
with high current accuracy which applies to single
stage step-down power factor corrected LED
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.
JW1765 is supplied from the output directly, and
auxiliary winding is not needed.
JW1765 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
