It seems ir reduced now loop gain to >2 times vs iraudamp4. BTW, strange, that switching precision isn't so good, by the PSRR plot i guess UcD400's loop gain is 10-20 times lower, but THD 1kHz@20W higher only by 4 times, so UcD400's switching precision (in the factory position of dead time) looks like 2.5 times better at least..
