Hello,
I am confused about how buck regulator modules such as **broken link removed** on ebay, work successfully with as much adjustment as they have. The datasheet is very specific about the inductor selection and the range of input/output voltage for a given inductor is much smaller than this module says it supports.
How is it that a fixed design such as this can work well, when input and output voltage can vary so much, and what is the side effect of the inductor and capactior value being fixed.
In addtion to this, the TI webpage for this device says
"Recommended alternative parts
LM43603 - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device. Synchronous 36V, 3A Regulator - Higher efficiency, Low Quiescent Current, Smaller Solution Size"
Would this work well in a similar situation with fixed component values and a large input/output range?
