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.
