Barrel Jack Dual Supply - Dual Ideal Diodes _MAKE_COMP_HEATSINK Controller: ST7920Add redundant power to Mini PCs, routers, monitors, CCTV and other barrel jack powered devices, using multiple power supplies! Power from the IN1 and IN2 barrel jack connectors goes via MOSFET "Ideal Diodes" to the OUT barrel jack. The ideal diodes prevent power from being fed back into either barrel jack. It will draw power from the supply with the highest voltage and if the voltages equalise (due to the current draw) it will share the load over both
