BL8345C High PFC BUCK LED Driver GENERATION DESCRIPTION BL8345C 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. BL8345C 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. BL8345C integrates 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.
