用于 LED 照明的步进调光准谐振初级侧电流模式控制器

NCL30081是一款PWM电流模式控制器，用于隔离型反激及非隔离降压-升压恒流拓扑结构。这控制器采用准谐振模式工作，以提供高能效。由于采用新颖的控制方法，NCL30081能在初级端精确地对LED电流进行稳流，这就省去次级端反馈电路、偏置及光耦。这控制器集成了5步对数调光功能，使LED灯泡能够采用标准壁式开关来进行调光。 Primary Side Sensing\nNo opto-coupler or secondary control circuitry\nWide VCC Range\nSimplifies support for a broad range of LED forward voltages with one transformer design \nPrecise LED Current Regulation of±1% typical\nNo need for binned forward voltage LEDS or production trimming for curren;
