Stability is a critical issue in designing DC/DC converters. The stability of a buck converter (Figure 1) is determined by the feedback loop compensator GCOM and the output power filter GLC. Nowadays, most PMIC manufacturers provide internal or external compensators, which are optimized for specific values of inductors and capacitors in the output power filters. […]
