AL8807AEV1 EVALUATION BOARD REFERENCE DESIGN

The AL8807AEV1 is configured to the reference design in Figure 2.

The operating voltage is a nominal 36V. The nominal current is set at 680mA with a 0R15 sense

resistor R1. The circuit operates in continuous mode at approximately 188kHz, with a 68uH inductor

and one LED.

For Analog dimming, the CTRL pin may be driven between 0.25V and 2.5V adjusting the output

current from approximately 10% to 100% of ILED. Shorting R3 will connect the test pin CTRL directly to

device pin CTRL, if required.

For other reference designs or further applications information, please refer to the AL8807A

datasheet.
