TPS55340: slva559 Fig.10 vs Fig. 1 (Load regulation)

PAN-M

Part Number: TPS55340

"If the output does not need to be tightly regulated, a bias winding can be used to drive the FB pin and error amplifier of the TPS55340." is written in slva559 Application Report.

How much is there difference in between Load regulation of primary side FB and the second side FB of this case (Fig.1 vs Fig.10)?

Hi Pan-M,

Thank you for the question. In PSR, the secondary output is cross regulated and its voltage may vary up to +/-10% over the entire load range.

Thanks,
