LARGE VALUE X2Y® IN DC-DC CONVERTERS
All commonly deployed DC-DC converter topologies: Buck, boost, flyback, SEPIC (Cuk topology is rare)
have at least one switched port. Parasitic capacitance across filter inductors passes
high frequency switching noise to filtered ports HF noise propagation through filtered and switched
ports is proportional to filter capacitor mounted ESL at each.
The unique construction of X2Y® capacitors results in essentially constant mounted ESL in larger body parts such as 1206, as in smaller body parts such as 0603.
Enables massive improvement in filter performance w/o extra magnetics
