Cxle8452 is a single-stage, high power factor, source side control AC to DC LED driver chip By using the special technology a few electrical information of the peripheral devices at the source side is needed

Cxle8452 is a single-stage, high power factor, source side control AC to DC LED driver chip. By using the special technology, only a few electrical information of the peripheral devices at the source side is needed, and the LED current can be precisely modulated without the need of optocoupler and the secondary side induction devices. The cxle8452 integrates the success rate factor correction function, which works in DCM (intermittent current mode) and constant off time mode, and can achieve very small total harmonic distortion current. Cxle8452 implements various protection functions, including over-current protection (OCP), over-voltage protection (OVP), short circuit protection (SCP) and over temperature protection (OTP), etc., to ensure the reliable operation of the system
