LED Driver
The LEDD10_24 is a series of step-down constant current source designed for
driving high power LEDs. With high efficiency, wide input voltage range, high-
temperature environment, functional and so on. Contains a PWM dimming, analog
dimming and remote shutdown capabilities.
It is widely used in LED illumination areas such as backlight and 12V, 24V, 36V
automotive lighting, landscape lighting, special lighting controls, commercial
lighting, street lighting, home lighting and other lighting systems.
