Diodes new out of the LED drive to reduce the electromagnetic interference of low-cost lamps

Diodes company launched AL8807 step-down switching mode LED driver. The high switching frequency up to 1MHz, with a switch to strictly control the rise and fall time, designed to reduce electromagnetic interference low cost MR16 LED lamps (EMI) and design. To achieve high output power requirements, this driver can operate between 6V to 30V input voltage, providing up to 1A constant current for up to eight series LED.

The drive current accuracy is + 5%, can meet the requirements of most low voltage lighting applications, and can improve the brightness between the lamp and the lamp in the lighting system of LED 3W collocation. The efficiency of this drive is as high as 96%, the output current setting is simple, just use an external resistor.

Through changing the drive control of DC voltage input or pulse width modulation (PWM) signal, users can adjust the LED brightness, but also to avoid the over current LED. The PWM dimming ratio of AL8807 is, and the range of DC signal dimming is from 16% to 100%, which provides users with flexible and wide range of brightness control.

AL8807 LED driver using SOT25 package for the small area of the MSOP-8EP package is to be launched.
