Cxle87164n cxle87164a cxle87164 is a step-down LED constant current driver working in the fixed off time control mode, which is used to drive multiple LEDs efficiently

Cxle87164n cxle87164a cxle87164 adopts the closed-loop constant current mode of average current type, and the output current is not sensitive to the change of inductance when the system is applied. This greatly improves the constant current accuracy of the output current, especially suitable for 8 ~ 80V input voltage range of non isolated step-down LED constant current drive circuit. Cxle87164n cxle87164a cxle87164 internal integrated power tube can set the average current of LED output through external resistance, and realize the high and low light mode switching function of LED output through mode pin external high and low level.
