Beschreibung
The AL8862QEV1, Figure 1, is a double sided evaluation board for the AL8862Q step-down, or ‘buck’, LED driver with internal switch in the SO-8EP package. The evaluation board is preset to drive1000mA 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 AL8862Q is 1000mA)
