Dear Sir/Madam,
I have four supplies +1V2, +1V5, +2V5 and +3V3.
+1V5, +2V5 and +3V3 are LMZ22003.
+1V2 is LMZ3170.
+1V5, +2V5 need to track +3V3. +1V2 needs to be enabled when +2V5 reaches 80% ie +2V.
The attached diagram shows tracking for LMZ22003 based on the data sheet and my understanding.
Comments welcome.
For the delayed startup of LMZ3170 what would be the best option?
comparator from +2V5 supply trip point +2V and connected to INH/UVLO pin via FET.
Comments welcome.
Regards Grant
