YauDL – Yet Another Useless Dummy Load
Posted August 22, 2015 by Chris
"The concept is pretty simple. It is a constant current sink controlled by 2 opamps. Two paralleled logic level MOSFETs do the heavy lifting (heatsink!). Another pair of paralleled P-MOSFETs + a Zener diode act as reverse polarity protection. A capacitor is used to keep the first opamp from oscillating."
