AL8807EV1 EVALUATION BOARD USER GUIDE

DESCRIPTION

The AL8807EV1, Figure 1, is a double sided evaluation board for the AL8807 step-down, or ‘buck’,

LED driver with internal switch. The evaluation board is preset to drive 680mA into a single LED, or

multiple LEDs, the maximum number of which depends on their total forward voltage drop and the

supply voltage. (The maximum drive current of the AL8807 is 1000mA)

The operating voltage is nominally 30 volts, but it can be reduced to a minimum of 6 volts. The 68uH

inductor used in the circuit is based on this nominal supply. The evaluation board should be

connected as in Figure 1 below.

Note: The evaluation board does not have reverse supply protection.

The nominal current, 680mA, is set with the 0R15 sense resistor, R1.

Terminal CTRL provides a connection point for DC or PWM dimming and shutdown.

Warning: At 30V nominal operation with 680mA output, the LED will be hot and very bright
