1. An apparatus comprising:
a precharge switch that selectively enables or disables precharge current from a Direct Current (DC) source to a capacitor;
a comparison circuit that generates a switch control signal to continuously control the precharge switch, wherein the switch control signal is generated based on a comparison between a scaled version of a circuit voltage and a reference voltage; and
a reference circuit that receives a precharge command signal and generates the reference voltage, wherein the precharge switch changes state in response to the precharge command signal changing state.
