A system is described. The system includes a control transistor, a voltage source, a feedback node connected between a drain of the control transistor and the voltage source, a plurality of resistors connected between the voltage source and ground, and a control node connected to a gate of the control transistor. The resistors include a first series-connected set of resistors associated with the control transistor being biased and a second series-connected set of resistors associated with the control transistor being unbiased. During a startup period, the control node is configured to bias the control transistor to select the first series-connected set of resistors, thereby increasing a voltage level of the voltage source to a boosted VCC voltage. After the startup period, the control node is configured to unbias the control transistor to select the second series-connected set of resistors, thereby decreasing the boosted VCC voltage to a normal VCC voltage.

Voltage source kickstart circuit for powering integrated circuits

A power supply comprises voltage regulation circuitry, a load-share controller, and overcurrent protection circuitry. The voltage regulation circuitry is configured to output a regulated voltage. The load-share controller is configured to control the voltage regulation circuitry to adjust the regulated voltage responsive to a load-share voltage signal (LSV) that indicates an amount of load current being delivered to a load. The overcurrent protection circuitry is configured to selectively couple the regulated voltage to the load. When the load current exceeds a threshold current, the overcurrent protection circuitry is configured to decouple the regulated voltage from the load. While the regulated voltage is decoupled from the load, and when the LSV signal indicates that load current is being delivered to the load by a different power supply, the overcurrent protection circuitry is configured to recouple the regulated voltage to the load.
