### Supply Chain Context
When a point-of-load rail goes on allocation, the fastest fix is to conduct a parametric search. Filter the search on input range, output current, and package, then sort by stock, and pick the part that lands on the same footprint. This way, the board does not change and the build moves ahead. However, this workflow produces buck converter alternatives that fit the footprint but behave differently once powered. Texas Instruments’ TPS54302 is a useful example. The device is a 4.5 V to 28 V input,
