AL8808 LED Driver

Diodes' AL8808 provides protection against a number of potential faults within a lamp

Image of Diodes Incorporated's AL8808 LED DriverDiodes introduces a simple, cost-effective LED driver for high-brightness LED lamps. The AL8808 is Diodes' latest high-brightness buck LED driver to meet the demands of latest low voltage LED lamps. The AL8808 provides protection against a number of potential faults within a lamp; including:

  • Over-temperature condition - switches itself off
  • Open-LEDs - automatically stops switching
  • Short-LEDs - continues switching but at reduced duty cycle minimizing power dissipation
  • The AL8808 can operate up to 1 MHz, reducing the size of external components. The small TSOT25 package size, coupled with the need for only four external components, produces a small solution footprint. The accuracy, temperature range, and cost make it ideally suited for cost sensitive lighting applications.

    Features Applications
    • Reduced switching noise and ringing
    • Open-LED, short-LED, and overtemperature protection
    • Small footprint, TSOT25 packages
    • 5% initial average LED current accuracy
    • Simple PWM dimming And Analog dimming on the CTRL pin
    • General illumination
    • Multi-substrate LED driving
    • Driving of parallel LED chains
    • MR16 lighting
    • SELV lighting
