TPS2393 200W ATCA Hot Swap Reference Design (TPS2393ATCA)
This reference design controls the dual -48 Volt power interface for a 200 Watt board in compliance with ATCA requirements. Although similar to the standard TPS2393 design, a number of components have been added to satisfy ATCA energy storage requirements and to protect the pass FET. These changes accommodate the large energy storage requirements of ATCA and improve board survivability. Nominal values for UV/OV and over current thresholds, as well as fault and ramp timing, are presented. If the designer needs to change any of these parameters the procedures are thoroughly covered in UserвЂ™s Guide SLUU155.
