Constant on-time control has been widely used due to its advantages of fast transient response and light load efficiency. However, the control scheme is intrinsically unstable if the output capacitor''s equivalent series resistance (ESR) is not large enough, which needs ripple injection techniques to enhance loop stability. The traditional passive ripple …

Ceramic Capacitors. Ceramic capacitors are also called as "Disc-capacitors". Like electrolytic, these are also the mostly used type of capacitors. A ceramic capacitor is constructed with two or more alternating layers of ceramic and a metal.Here the ceramic acts as its dielectric and metal acts as its electrodes.
These ceramic capacitors have high capacitance density, i.e., you can reach a high capacitance in a small volume. In general, class 2 ceramic capacitors are used for smoothing, bypassing, coupling, and decoupling applications.
