Cxle86185 is a step-up LED driver chip, which can drive up to 39 (3 strings and 13 parallel) led lights from 5V power supply. Cxle86185 adjusts the LED current through an external current

Cxle86185 is a step-up LED driver chip, which can drive up to 39 (3 strings and 13 parallel) led lights from 5V power supply. Cxle86185 adjusts the LED current through an external current sensing resistor with a fixed operating frequency and current mode. 110mV feedback voltage can effectively reduce power consumption and improve efficiency. Cxle86185 has the function of open circuit protection. Once the OV pin detects the occurrence of overvoltage, the chip will turn off the converter. At the same time, cxle86185 also includes the protection of under voltage locking, current limiting, overheat protection and other abnormal conditions to improve the reliability of the system
