Group DC-DC Converters

YAGEO Group (YAGEO, KEMET, Pulse) strives to support 90% of all the passive technologies required in circuit designs. DC-DC converters saturate the electronics industry and are used to either step or step down the voltage and current requirements of the next stage in the circuit. In every variation of the DC-DC converter, current sense resistors, diodes, inductors, precision voltage resistors, and capacitors are used.
