LED Driver

The LEDD24_24 is a step-down constant current sources for driving high-power

LED featured in high efficiency and wide range of input voltage, high

operating temperature, and act in PWM dimming, analogue dimming and

remote turn-off.

The product can be widely applied to fields such as landscape lighting, specially-

controlled lighting, backlight, business lighting, street lamp lighting, domestic

lighting and automobile lighting.
