AL8807MP-13

The AL8807MP-13 is a High Efficiency Buck LED Driver designed to drive LEDs with a constant current. The device can drive up to 9 LEDs, depending on the forward voltage of the LEDs, in series from a voltage source of 6 to 36V. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors. The AL8807 switches at frequency up to 1MHz with controlled rise and fall times to reduce EMI. This allows the use of small size external components, hence minimizing the PCB area needed. Maximum output current of AL8807 is set via an external resistor connected between the VIN and SET input pins. Dimming is achieved by applying either a DC voltage or a PWM signal at the CTRL input pin. An input voltage of 0.4V or lower at CTRL switches off the output MOSFET simplifying PWM dimming.

• LED driving current up to 1.3A
• Better than 5% accuracy
• High efficiency up to 96%
• Optimally controlled switching speeds
• Operating input voltage from 6V to 36V
• PWM/DC input for dimming control
• Built-in output open-circuit protection
