I have multiple adjustable DC/DC buck converters in a design and I'm looking to save lines in the BOM for assembly. Is there any significant drawback to using more than two resistors in a feedback network?
For example, if I need R1 to be 300k and R2 to be 150k can I replace a single 300k R1 resistor with 2 150k's in series? Assuming I use high precision resistors and can tolerate an increased ±% output tolerance what other negatives might I encounter?
Same question applies for resistors in parallel.
