Hi,
As recommended by datasheet - I am using RCFG1/2/3 resistors with a tolerance of ±1%, temp coefficient better than ±200 ppm.
However, for my nominal selections of (SEL=High) 1.8V (CFG1=0-ohm), I get 1.794V, - and - for 3V (CFG3=13.3K), I get 2.997V.
So, my question is - in order to avoid potential risk of triggering brown-out on certain parts powered by this buck-boost; can I use
resistor values slightly (few ohms) higher than the nominal values listed in Table 7-2 and 7-3? Such as 10-100 mOhm in place of
0-ohm.
Please advise. Thanks for your timely attention and help.
