Cxle8459a cxle8459b cxle8459c realizes various protection functions at the same time, including OCP, SCP, OVP and OTP, so as to ensure the reliable operation of the system

Cxle8459a cxle8459b cxle8459c realizes various protection functions at the same time, including OCP, SCP, OVP and OTP, so as to ensure the reliable operation of the system. Cxle8459a is a driving switching power supply designed for LED lighting applications. It adopts the primary side feedback technology without auxiliary winding, without secondary feedback circuit or compensation circuit. Internal integration of 600V high-voltage power switch, adjustable led open circuit protection (OVP) makes the system simple and reliable. The constant current control and compensation technology adopted by cxle8459a, LED output current accuracy is within ?5%, has excellent linear adjustment rate and load adjustment rate, and is not sensitive to the change of transformer winding inductance
