Cxle8454a cxle8454b is equipped with 700V high-voltage power tube, which simplifies the peripheral circuit realizes various protection functions at the same time including over-current protection

Cxle8454a cxle8454b is equipped with 700V high-voltage power tube, which simplifies the peripheral circuit. Cxle8453a cxle8453b realizes various protection functions at the same time, including over-current protection (OCP), over-voltage protection (OVP), short circuit protection (SCP) and over temperature protection (OTP) to ensure the reliable operation of the system. Mcxle8454a cxle8454b is a single-stage, high power factor (PF), primary control AC to DC LED driver chip. Cxle8454a cxle8454b integrated on-chip power factor correction (PFC) function operates in intermittent conduction mode, realizing high power factor and low harmonic distortion (THD). With special control technology, LED current can be precisely modulated without optocoupler and secondary inductor
