Testing a DC-DC Converter Module


I needed a 5V rail for a project that would be sourcing current for a USB battery charger from a 12V wall adapter. At these kinds of loads (<= 1A) a linear voltage regulator like the LM7805 is impractical, as it has to drop a lot of voltage, and dissipate a lot of power. That’s why I opted to use a buck converter instead.
