LED drivers reduce interference with low-cost lamps

Diodes company introduces AL8807 Buck switch mode LED driver. Its switching frequency is as high as 1 MHz, with strictly controlled switching rise and fall times, specially designed to reduce electromagnetic interference (EMI)And design. In order to meet the requirement of high output power, the driver can operate between 6V and 30V input voltages, providing a constant current of up to 1A for up to eight series LEDs. The current accuracy of the driver is 5, which can meet the requirements of most low voltage lighting applications and improve the brightness matching between lamps in the 3WLED lighting system. The efficiency of the driver is as high as 96, and its output current is simple to set, only one external resistor is needed. By changing the DC voltage or pulse width modulation (PWM) Signal, the user can adjust the brightness of the LED and avoid LED overcurrent. The PWM dimming ratio of AL8807 is 1000:1, and the DC signal dimming range is 16 to 100, providing users with flexible and wide light brightness control range.
