MegaLoad – Constant current/power/voltage programmable load
Engineering & Technical Design 3d-design, altium-desiger, 3d-printing
PCB design of a constant current / voltage / power load.
The Design features:
-Dynamic gain switching using the main processor (Cypress Psoc 4) internal mux.
-Dual channel current measurement
-Isolated I2C interface bus using the Ardum1250 chip from Analog DevicesThe design features an off the shelf Intel 775 socket style mounting bracket for CPU heat sinks. This is done to stretch the safe operation area of the two IXYS L2 mosfets and reduce the overall bill of materials cost.
