Cxle8455a cxle8455b cxle8455c realizes various protection functions at the same time, including over-current protection (OCP), over-voltage protection (OVP) short circuit protection

Cxle8455a cxle8455b cxle8455c 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), so as to ensure the reliable operation of the system. Cxle8455a cxle8455b cxle8455c is a single-stage, high power factor (PF), primary control AC to DC LED driver chip. The PF function of cxle8455a cxle8455b cxle8455c integrated chip works in critical conduction mode, realizing high power factor and reducing switching loss of MOSFET power supply. By using the special control technology, the LED current can be accurately controlled without the auxiliary side induction devices such as optocoupler. Cxle8455a cxle8455b cxle8455c has built-in 600V high-voltage power tube, which simplifies the peripheral circuit.
