TPS40400: Power saving method

Part Number: TPS40400
Other Parts Discussed in Thread: TPS549B22, TPS549D22, PMP21440, LMG1210, TPS40101, TPS40322

Hi Team,

Would you advise does TPS40400 have power saving internal register setting or 

external part which can save power?

My customer want to reduce Ivdd below to less than 4mA which is required by product.

Any advice should be highly appreciated.


Best regards,
