LED Driver

The LEDD10_24_P 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, ana-

log dimming and remote shutdown capabilities.

It is widely used in LED illumination areas such as backlight and 12V, 24V, 36V au-

tomotive lighting, landscape lighting, special lighting controls, commercial

lighting, street lighting, home lighting and other lighting systems.
