Diodes Incorporated's LED Driver Reduces EMI in Low-Cost Lamps
The driver's current accuracy of 5% means it will meet the requirements of most general low-voltage lighting applications and lead to an improvement in inter-lamp luminance matching in 3W LED lighting systems. The driver is up to 96% efficient and its output current is simple to set using a single external resistor.
Dimming control is via the application of either a DC voltage or PWM signal on the driver's control input, which also protects against any over-driving of the LED current. The AL8807's 1000:1 PWM dimming ratio and DC dimming range from 16% to 100%, provide users with flexible and wide-ranging lamp brightness control.
The AL8807 is available in the small footprint SOT25 package and will soon be available in the MSOP-8EP package. For further information, visit the Company's website at www.diodes.com .
