SILICON LABS CONFIDENTIAL
Revision Notes
26 August 2015:
Added B5 indicating the Si3402-B-EN1 samples should be run only at room temperature
Clarified Buck (Non-Isolated) case R7 to standard value 47kΩ and relaxed to 20% tolerance
28 October 2015:
Previous version silicon errata resolved
Several components in the change list updated
Document renamed “Si3402-B RevA3 Change List_<YYYYMMDD>”
24 November 2015:
M2 and M6 components updated
Aligns with production Si3402-B-GM silicon
08 December 2015: (Version 0.3)
Changed title of doc and name of file
Clarified M7-M9 changes with regard to R8
21 March 2016: (Version 0.4)
Updated M3, the 3.3V Isolated Flyback case.
o Explanation: 3.3V Flyback compensation was updated to address a small overshoot
condition under no-load conditions (3.66V is allowed, the overshoot was 3.73V). The
problem is fixed with revised compensation with a resulting overshoot of about 3.5V.
o If a no-load condition is unlikely, the customer may keep the original M3 change
recommendation:
C8, R9 & C23 are not need—Do not populate them
C9=3.3nF, C21=15nF, R12=0 & R8=0 (place zero Ω resistors)
Replace D2 (DFLT15A) with DFLT30A
