AL250
11.0 Power Consumption
The AL250/251 works at both 5V and 3.3V. The following table shows the current consumption of
the AL250/251 itself and that of the whole EVB with power supply at single 5V, or 5V and 3.3V
mixed (3.3V for the AL250/251 only).
+5V
+3.3V for AL250
+5V for the rest
AL250/251 chip
92 mA (typ.)
55 mA (typ.)
AL250 EVB
280 mA (typ.)
140 mA (typ.)
Please be reminded that when lower power supply is used, the pull-down resistance to the RSET pin
has to be adjusted to compensate accordingly. The lower the supply voltage is, the lower the pull-
down resistance has to be. The ideal resistance value can be achieved by adjusting the RGB output to
be 0.7V peak-to-peak or higher to obtain better output brightness and contrast.
