概览

NCL30186 是一款 AC-DC 功率因数校正的反激控制器,用于隔离和非隔离“可智能调光”恒定电流 LED 驱动器。该控制器以准谐振模式运行,可提供最佳能效。该电流控制算法支持反激、降压-升压和 SEPIC 拓扑结构。由于新型控制方法,该器件能够严格调节初级侧的恒定 LED 电流。因此无需辅助侧反馈电路、偏置和光耦合器。 该器件与极少数量的外部部件进行高度集成。内置了一组丰富的安全保护功能,简化了设计。该器件特别适用于非常紧凑的空间效率设计,通过专门的调光输入支持模拟和 PWM 调光,用于控制平均 LED 电流。为了确保在高温下可靠的运行,还提供了用户可配置的电流折回电路。NCL30086 采用 SOIC10 封装,与标准 SOIC8 具有相同的本体尺寸。
