   CXLE8299 is a single-stage，primary side control AC-DC LED driver with active jWd嘉泰姆

power factor correction. integrates on-chip PFC circuit operates in critical jWd嘉泰姆

conduction mode (CRM) to achieve high power factor and reduce the power MOSFET switching loss.With Shouding Proprietary control technique, precision LED current is achieved without secondary side sense and feedback circuit including opto-coupler.CXLE8299 provides various protections, such as over current protection (OCP), over voltage protection (OVP), short circuit protection (SCP)and over temperature protection (OTP), etc, to improve system reliability.jWd嘉泰姆
