     CXLE83170B CXLE83170C is a highly integrated power switch with constant current (CC) control for LED lighting applications. The IC utilizes Quasi-Resonant (QR) Buck topology with active PFC control for high PF, low THD, and high efficiency. CXLE83170B CXLE83170C integrates 500V power MOSFET with high voltage startup and IC power supply circuit, which requires very few external components. The IC senses the inductor current during the whole switching cycle, which can achieve high precision CC control with excellent line and load regulation. CXLE83170B CXLE83170Cintegrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Thermal Foldack (OTP), Output Over Voltage Protection (OVP), LED Open/Short Protection, etc. CXLE83170B CXLE83170Cuse SOP-7 package.
