Abstract

A variable electronic load tester circuit comprising a control circuit and a variable electronic load circuit coupled to the control circuit to receive a voltage from a power supply and present a load to the power supply. The variable electronic load circuit comprises a plurality of transistors connected in series and operable as variable resistors. The control circuit is to control a resistance of the variable resistors to control the load presented to the power supply. The control circuit comprises an error amplifier to compare a first voltage to a feedback signal and an output signal indicative of a difference between the first voltage and the feedback signal. The output signal is to control the resistance of the variable electronic load circuit to vary the load presented to the power supply. The feedback signal is proportional to a current flowing through the variable electronic load circuit.
