AL8860EV2 EVALUATION BOARD USER GUIDE

Details

TopologieAbwärtswandler
Eingangsspannung4.5-40 V
Schaltfrequenz1000 kHz
IC-Revision1

Beschreibung

The AL8860EV2, Figure 1, is a double sided evaluation board for the AL8860 step-down, or ‘buck’, LED driver with internal switch. The evaluation board is preset to drive 1.5A 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 AL8860 is 1.5A)
