Cxle86112h is a high precision segmented linear constant current LED control chip, which integrates the high voltage rectifier and JFET high voltage power supply function. It is mainly used to drive high voltage and low current LED lamp strings powered by the municipal power supply. As no electrolytic capacitor and magnetic components are needed, LED driver can achieve small volume, long life and meet EMI regulations. Cxle86112h can precisely set LED current through external resistance, and the chip can reduce thd by optimizing the current when conducting in sections. In the application of 220 V mains power input, it is recommended to set the LED current below 40 ma. Cxle86112h has over temperature regulation function. When the input voltage is too high or the LED current is too high, this function will reduce the output current. The over temperature point can be set by external resistance. Cxle86112h integrates the input line voltage compensation function. When the input line voltage is too high, cxle86112h will reduce the output current according to the external compensation resistance to ensure that the input power basically does not change with the line voltage.
