Changes
#1 Replaced EN63A0QI (U14, U15) by LTM4638EY#PBF
Type: Schematic change
Reason: Enpirion DCDCs are discontinued.
Impact: None. Maximum continuous output current increased from 12A to 15A per DCDC.
#2 Replaced EP53F8QI (U6, U8, U16) by TPS82085SIL
Type: Schematic change
Reason: Enpirion DCDCs are discontinued.
