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

device pin CTRL, if required.

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

datasheet.
