All DC/DC power supplies comprise closed-loop systems. In any closed-loop system, control theory dictates the need for adequate gain and phase margin for overall system stability. Trade-offs have to be made between phase and gain margin and transient response by adjusting the feedback gain for a given power stage.
Some power IC controller manufacturers have designed their products with internal loop compensation. Hence, the user is forced to select power stage components ...
