In an example configuration, a power supply manager receives an output current value representing an amount of output current supplied by one or more power converter phases to a load. The power supply manager also receives a duty cycle value representing a duty cycle for controlling operation of the at least one power converter phase. The power supply manager produces an estimate of input current supplied to the power supply circuit based at least in part on multiplying the output current value by the duty cycle value. Contrary to conventional methods such as physically measuring an input current using complex measuring circuitry, embodiments herein include utilizing parameter information such as output current information and duty cycle information to deduce an amount of input current.
