电压开关驱动器，恒流驱动器，闪光灯LED驱动器LED controllers Voltage-switch drivers, constant-current drivers, and Flash LED drivers LEDs are used in a wide range of applications, from low-end status indicators to high-end video displays. System designers often need the ability to control these LEDs, but can’t afford to tie up the system processor to do so. NXP’s LED controllers solve this problem, performing a variety of control tasks while offloading the system processor. Having sent instructions to the LED controller, the processor is free to engage in other tasks or go into a low-power state. NXP’s LED controllers offer a variety of features needed in LED-driving applications. Some of these features include: } Blinking and dimming capability } Pulse-width modulation (PWM) for LED control } Color mixing capabilities } Fast-mo……
