1. A power management system for a vehicle, comprising:
a power source;
switching circuitry electrically coupled with the power source and configured to selectively provide power from the power source to at least one load;
a first converter electrically interposing the power source and the switching circuitry and configured to provide the power to the switching circuitry, the first converter having a first power output threshold;
a second converter electrically interposing the power source and the switching circuitry and configured to provide the power to the switching circuitry, the second converter having a second power output threshold lower than the first power output threshold; and
control circuitry configured to:
in response to a key-off state of the vehicle, control the switching circuitry to supply the power to the at least one load;
compare the power drawn from the second converter by the at least one load to the second power output threshold; and
communicate an output to limit the power drawn from the second converter by the at least one load in response to the comparison.
