N2 - This paper introduces a new hardware efficient auto tuning for digitally controlled average current-mode (ACM) controllers. The auto-Tuning procedure extracts the required coefficients of the ACM controller to achieve tight voltage regulation as well as closed-loop dynamic performance that may be defined by the end-user. System stability is facilitated for wide operation range under parameters uncertainties and other variations. It is found that information of the change in the state-variables suffice for a successful and accurate closed-loop operation without the need of a detailed extraction of the values of the passive components. The algorithm is applicable upon power up of the SMPS and has been integrated into the soft-start routine of the converter, assuring tight and stable regulation of the output voltage under all scenarios. The effectiveness of the new digital auto-Tuning ACM controller is demonstrated on an experimental 500kHz, 12V-To-1.2V digitally controlled synchronous buck converter.
