日落调光LED司机

The iW3640 is a highly integrated LED driver for off-line, sunset dimming solid state lighting applications up to 25W. With a dual driver output, the iW3640 allows for additional amber LEDs to be used in parallel with the main white LEDs, providing LED color mixing to create a dimming profile that accurately recreates the warmth of incandescent dimming all in a single controller IC. By integrating the secondary driver and using the digital engine to control the transitions, the iW3640 removes the cost of an external MCU and its dedicated power supply and provides an easy-to-use solution.

Flickerless™technology integrated, the iW3640 allows for full 1%-100%, flicker-free phase-cut dimming while working with most dimmer types, including leading-edge, trailing-edge and digital dimmers. The device is fully featured and with its two-stage approach, offers a powerful combination of high power factor (>0.95), low THD (<15%) and low ripple voltage (<20%).

IW3640完全保护,包括内置过温保护段,监控外部NTC设备,并在高温下缩小输出LED电流,允许LED照明器的可靠和可预测的操作寿命。有关OTP降额函数的更多信息,请单击here
