产品概述 返回TOP
The CXLE8380 is a constant current LED regulator with high current accuracy which applies to single stage step-down power factor corrected LED drivers. With outside power MOSFET, which can significantly simplify the design for High Power LED lighting application. 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. The CXLE8380 is supplied from the output directly, and auxiliary winding is not needed. The CXLE8380 has multi-protection functions which largely enhance the safety and reliability of the system, including VDD over-voltage protection, VDD UVLO, short-circuit protection, LED open protection, cycle-by-cycle current limit and over-temperature protection. The CXLE8380 available in SOT23-6 packages.
