BP3176BF 是一款适用于反激电路的隔离低PF可调光LED驱动器,支持PWM和模拟调光信号,全程模拟调光,可以实现高精度、无频闪的照明。 BP3176BF控制的反激电路工作在电感电流临界导通和准谐振模式,从而实现更高的转换效率和更低的电磁干扰(EMI),提高变压器的利用率。BP3176BF采用了先进的原边采样恒流算法,可实现优异的线性调整率和负载调整率,同时省去了次边反馈元件,简化了BOM数量和系统成本。
Advantage
支持 PWM 调光和模拟调光信号,调光深度低至5%,且低端可关断
输出电流基准精度士3%
深度调光时良好的批量一致性
内置软启动功能,输出电流无过冲
内置线电压补偿和负载补偿
各种保护功能
Application area
LED 面板灯、格栅灯
LED 路灯
