Abstract: A power limiting circuit for power supply that is controlled by a power supply control module includes a shunt regulator having a reference input operatively connected to a voltage input that receives a voltage representative of the power supply control module connected thereto. The shunt regulator is biased on when the voltage at the reference input increases above a reference voltage established at the voltage input. A transistor is operatively connected to the shunt regulator and to an output operatively connected to the power supply control module and has a voltage that is representative of voltage operating the power supply control module. The transistor is biased on from the shunt regulator such that the shunt regulator and transistor form a latch when the voltage at the output reduces below an off voltage level to turn off the power supply, dropping the input voltage, and restarting the power supply in a restart cycle.
