Offline Step-down LED Controller With PFC and No Auxiliary Winding
DESCRIPTION
The JW®1765 is a constant current LED controller with high current accuracy which applies to single stage step-down power factor corrected LED drivers.
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 U...
