Systems and methods may provide for a transient response apparatus that includes a single stage conversion module having a power input, a power output, and a control input, and a compensation module including a feedback input. The compensation module may be coupled to the power input, the power output and the control input of the single stage conversion module. Additionally, a feedback module may be coupled to the power output of the single stage conversion module and the feedback input of the compensation module. In one example, the feedback module includes a loop controller having a plurality of programmable inputs and an error output, and a modulus unit coupled to the error output of the loop controller and the feedback input of the compensation module.
