Switching at a frequency of up to 1 MHz and ensuring closely controlled rise and fall times, the AL8807 buck LED driver is 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 6 to 30 V and provide up to 8 series connected LEDs with a constant 1-A current.
The driver features a current accuracy of ±5%, an efficiency of 96%, a PWM dimming ratio of 1000:1, and a dc dimming range from 16 to 100%. Provided in the small footprint SOT25 package and soon available in the MSOP-8EP package, the AL8807 output current is simple to set using a single external resistor.($0.40 ea/1,000 available now)
