SYSTEMS AND METHODS FOR ADAPTIVE INPUT CURRENT LIMIT CONTROL

A power system configured to provide electrical energy to information handling resources of the information handling system, and a management controller communicatively coupled to the processor and the power system. The power system may include a buck voltage regulator configured to receive a DC input voltage from an AC adapter to generate a DC main voltage, a battery for powering components of the information handling system, and a charger configured to charge the battery from the DC main voltage. The management controller may be configured to receive from the buck voltage regulator an input current signal indicative of a first electrical current drawn by the buck voltage regulator from the AC adapter, perform a comparison of the input current signal to a maximum current rating of the AC adapter, and control a second electrical current drawn by the charger from the DC main voltage based on the comparison.
