Specify Gain and Phase Margins on All Your Loops 

When purchasing a power supply, you should specify the gain and phase margins of all feedback loops within a power supply. The main loop should be specified for stability margins not only as shipped with local sense, but with remote sense and extra output capacitance too. Your specifications should also include regulated and the margins of the current limit loops if the supply has active current limiting. Learn more about developing specifications for your gain and phase margins by downloading this white paper. In this white paper, you will learn:
