That's not going to work well - different regulators have wildly different abilities to deliver current which is the whole reason why modes are so fuzzy and hard to use in the first place. A high power load for a low noise regulator designed to feed analogue circuits might not even make it out of the lowest power LDO mode of a DCDC designed to supply the main application processors in the system or (more relevantly) provide the main step down for a bunch of LDOs. --o/BvujNCPFVhiGON Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAlt0CscACgkQJNaLcl1U h9B+Kgf9HS5XAoJXshcYgt2CrThQDosEbnz78XdZ2lGsN6BNUXsumLPsHBnX3rzl pyhsw60PmtVys2LqrZLnHnJ4GFh2Zv1wK3vqFHVJwW4Pvm1j2IoAYzIplZCVggtJ qgTD++1e7JoIBlK5NU2UbqDTcueKijSqLVmzTuBYM/asgEb/sWRkav8f6ldMxa70 FflcQrxbtjTkPhKZoeyipt4mSgpor8f/FJBG45UK1fePouIFy97G1phNimXUCCSR CKxrdrx7VrcDhjdoEcyGb2NwAyRS7UB3n2qX8j7RJ7W3mJ6z2WJM+ejofu4U+ILE nqbVelxHMe4eKDFD6/btdJ9bY4xKvw== =0y/O -----END PGP SIGNATURE----- --o/BvujNCPFVhiGON--
