EQUIVALENT SERIES RESISTANCE OF SMOOTHING CAPACITOR AND STABILITY OF
DC/DC CONVERTER
The equivalent series resistance (ESR) of the smoothing capacity in a DC/DC converter has a great effect on the loop phase characteristics.
The ESR causes a small delay at the capacitor with a series resistance of 0 (Figures 8 and 9), thus improving system stability. On the other
hand, using a smoothing capacitor with a low ESR reduces system stability. Therefore, attention should be paid to using semiconductor electrolytic
capacitors (such as OS capacitors) or tantalum capacitors with a low ESP (Phase margin reduction by using an OS capacitor is explained on
the next page.)
