General Description

The AnyVolt3 is a miniature step up / step

down switching DC-DC converter. The output

is adjustable from 3 to 24V.

The output voltage is set with a small screw

potentiometer on the side of the AnyVolt3.

Once the output voltage is set, it does not

matter whether the input voltage is higher,

lower, or the same as the desired output.

The AnyVolt3 uses four screw terminals and

requires jumpers or stripped wires to operate.

Example: The output of the AnyVolt3 in a certain project is 12V, and it is supplying a constant .99A. What will the input current be if I am powering the AnyVolt3 with a 5V supply? “Power = Volts * Amps” 12V*.99A = 11.88W So the power output is 11.88W. “Output power / efficiency = Input power” Looking at the efficiency curves of the AnyVolt3 datasheet, efficiency is 79.75% in this situation. 11.88W / 0.7975 = 14.90W So the power going into the AnyVolt3 is 14.90W “Power / Volts = Amps” 14.9W / 5V = 2.

Additional notes AnyVolt3 uses a 25 turn worm gear driven potentiometer and cannot wiggle loose. Do not apply glue to the voltage adjustment pot. AnyVolt3 should be mounted at least 2 inches away from any circuitry that is sensitive to RF. For best performance, mount AnyVolt3 in an open space with some air flowing across it to keep it cool.
