概览

NCL30086是一款AC-DC功率因数校正的反激控制器，用于隔离和非隔离型的“智能调光”恒流LED驱动器。该控制器采用准谐振模式以提供最佳能效。这电流控制算法支持反激、降压-升压和SEPIC拓扑结构。由于新颖的控制方法，这器件能严格地对初级端电流进行稳流。这省去了次级端反馈电路、偏置和光耦。这器件集成度高，所需外部元件数极少。内置一系列强固的保护特性以简化设计。该器件专用于很紧凑空间的高能效设计，并支持模拟和PWM调光，使用专用调光输入以控制平均LED电流。为确保温度升高时可靠的工作，还提供用户可配置的电流反走电路。NCL30086采用与标准的SOIC8尺寸相同的SOIC10封装。
