Schematic Diagram
Setting Output Current
Output current is preset to 500mA for this board.
Output current can be re-programmed by selecting
R3 according to the following equation:
I OUT
=
R6
+
R1 + R8 −
R7 ⋅ R3
R7
⋅1V
However, the board must be forced cooled or
encapsulated using thermally conductive encapsulant
to operate continuously at output current higher than
500mA.
