Power supply switching regulator electrical circuit trimming methods. A trimming method includes assembling one or more components of a power supply switching regulator electrical circuit onto a printed circuit board having one or more electrical connections coupled to the said one or more components. An electrical parameter of the power supply switching regulator electrical circuit is then trimmed after the assembling of the one or more components of the power supply switching regulator electrical circuit onto the printed circuit board. The trimming of the electrical parameter of the power supply switching regulator electrical circuit includes removing a portion of the printed circuit board to break the electrical connection on the printed circuit board.
