Switching at a frequency of up to 1MHz and ensuring closely controlled rise and fall times, the AL8807 buck LED driver from Diodes Incorporated has been purpose designed to reduce EMI issues in the lower cost MR16 LED lamp market. To achieve required higher output powers, the driver can operate at input voltages between 6V to 30V and provide up to 8 series connected LEDs with a constant 1A current.
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 LED driver is provided in the small footprint SOT25 package and will soon be available in the MSOP-8EP package. Further information is available at www.diodes.com.
