An assembly language subroutine is provided for a microprocessor which is regulating the voltage level of a switching power supply. The subroutine provides a simple and fast response digital method of regulating a switching power supply during dynamic and static load changes. The subroutine is useful in conjunction with a microprocessor-controlled power supply such as that described in the preceding article. The subroutine serves in a digital control system in a manner analogous to a linear control system where the pulse-width change is proportional to the error.
