The ATLAS detector is set to undergo a substantial upgrade termed the “Phase-II” upgrade during the Long-Shutdown in preparation for the start of operation of the High Luminosity Large Hadron Collider (HL-LHC). This paper describes the development and implementation of the Phase-II upgrade low voltage power supply transformer-coupled buck converter (Brick) test bench. A large scale production of approximately 2048 finger low voltage power supplies, with an identical output voltage, is set to be undertaken in the year 2022. This production will culminate in the complete replacement of the LVPS Brick V7.5.0 currently installed within the Tile Calorimeter. Due to the location of the Bricks within the inner barrel of the TileCal their reliability is of the utmost importance. Therefore, the implementation of performance screening will be implemented and will involve the testing and certification of all Bricks produced.
