汇创佳电子代理BL8345B BL8345C

BL8345B 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.

产品简介BL8345B 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.
