[FAQ] TPS23755: What is the benefit of Primary Side Regulation (PSR)?

PSR allows for the output voltage to be regulated on the primary side of the transformer. This eliminates the need for feedback circuitry from the secondary side to the primary side and therefore reduces system level BOM cost as well as solution size. To learn more, please refer to the TPS23755 datasheet.
