Abstract
A method of optimizing a gain adjustment value Kadj for a digital controller in an isolated switched mode power supply. The power supply includes an opto-coupler having a current transfer ratio (CTR) within a range defined by a minimum current transfer ratio (CTR) and a maximum current transfer ratio (CTR). The method includes determining the CTRof the opto-coupler, determining an optimal gain adjustment value Kadjbased on the determined CTRof the opto-coupler, and storing the optimal gain adjustment value Kadjin the digital controller. The method can be performed by the digital controller or by a programming device external to the power supply.
