Overview
BL8345B
High PFC BUCK LED Driver
GENERATION DESCRIPTION
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.
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.
BL8345B integrates functions and protections of Under Voltage Lockout (UVLO), Cycle-by-cycle Current Limiting (OCP), Thermal ...
