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 control, and
SMD package which facilitates the installation.
It is widely used in LED illumination areas such as decorative light, special control
light, backlight, commercial light, streetlight, in-house light and car light, etc.
