DC DC Converters

DC-DC converters are a type of power converter that convert a direct current (DC) input source to a different DC output voltage. These converters are used to power electronic devices or provide power input into another power supply. DC-DC converters are used to provide a stable voltage from an unpredictable voltage from the source device or to reduce the amount of power loss from the output device due to variable input voltage.
