100 uF cap | GRM21BR60E107ME15L | C_1.1_OUT1, C_1.8_OUT2 | |
old inductor | MLZ1005M2R2WT000 | L1, L2 | |
new inductor | 74438343022 | L1, L2 | Recommended on datasheet |
1.1V DC-DC | S-85S1AB11-I6T1U | U3 | |
1.8V DC-DC | S-85S1AB18-I6T1U | U2 |
Note that the 1.1V DC-DC converters were missing so 1.0V DC-DC converters were used as a substitute.
