LED Driver

The LED16_24 is a series of step-down constant current source designed for

driving high power LEDs. It features high efficiency, wide input voltage range,

high operating temperature, PWM and analogue dimming, remote ON/OFF con-

trol, and SMD package which facilitates the installation.

It is widely used in LED illumination areas such as decorative light, special con-

trol light, backlight, commercial light, streetlight, in-house light and car light,

etc.
