Hardware designs by Michael Schwingen, michael at schwingen dot org
Similar to Analog Devices LB-013, this is a simple R-C-network that is useful when optimizing the loop compensation of switching regulators. I made this to use parts I had around (especially the 5-pin DIP switches), primarily because a nice PCB with silkscreen is a lot prettier than a bit of perfboard.
The PCB with all switches open has ca. 12pF of capacitance.
