Method and system for intelligent load line control of information handling systems

An information handling system, comprising:

• a processor subsystem having access to a first memory;
• an embedded controller comprising a secondary processor having access to a second memory, the second memory storing instructions executable by the secondary processor to:
• read information from the processor subsystem to identify a load factor;
• determine a linear load line impedance based on the load factor;
• enable linear load line control by setting the linear load line impedance in a voltage regulator subsystem;
• determine that a second range condition corresponding to a second range nonlinear load line impedance is satisfied, wherein the second range nonlinear load line impedance is greater than or equal to both the linear load line impedance and a first range nonlinear load line impedance;
• and
• enable nonlinear load line control by setting the second range nonlinear load line impedance based on the determination that the second range condition is satisfied, wherein nonlinear load line control with the second range nonlinear load line impedance has a first piecewise linear response.
