The SMM605 START pin must be inactive during power-up so
that the TRIM pin is high impedence. Once power is nominal,
the START pin can be active to start margin and ADOC
functions

VOUT
VTRIMlow=0.3V, VOSENSE=0.8V
The current through R3 is
ITRIM=(0.8-0.3)/RTRIM
(ITRIM)(R4) > 15% of VOUT
RTRIMmax should be no greater
then the calculated value
READY
For Example, If Vout=3.3V, R4=63.4K
15% of Vout=0.5V
ITRIM=8uA
RTRIM=62.5K so Rtrim should be
next value down from 62.5K
