上海贝岭一级代理：BL8345C 高PFC高效非隔离降压型恒流LED驱动芯片 辉锦电子

产品简介：

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. BL8345C use SOP-7 packag
