摘要： A system for scalable voltage ramp control for power supply systems. A system may comprise at least power supply circuitry, digital-to-analog (D/A) converter circuitry and a controller. The power supply circuitry may be configured to output a voltage to a load based on an input voltage provided by the D/A converter. The controller may be configured to control the D/A converter (e.g., to cause the D/A converter to provide the input voltage to the power supply circuitry) using a large range voltage ramp-up or a small range voltage ramp-up. Utilization of the large range voltage ramp-up or the small range voltage ramp-up by the controller may be based on, for example, a threshold voltage.
