Aug 30, 2025 · Below you will find an overview of all DC/DC converters from 54V to 48V DC direct voltage. These converters are stabilized, short-circuit proof and can operate with 54V DC input

In the 48V case, transistors and drivers that can handle at least 100V on the power nodes are a good choice. In a mild hybrid application, realizing the most efficient use of battery power is one of the keys to meeting miles-per-gallon (mpg) and CO2 emission targets. An efficient inverter starts with transistor selection.
Driven by AI and the associated high power requirements, datacenters are transitioning to 48 V intermediate bus converters, which require a complex power conversion process. For high power GPU and AI ASICs in this application, the conversion process starts with the power supply directly from the busbar to the accelerator card or baseboard.
Traditional 12V loads will continue to be supported thanks to DC-DC converters – either from a HV bus, or from a 48V battery; however, as loads migrate to 48V, the size of the 12V DC-DC converter may decrease over time as 48V becomes mainstream.
Replacing the isolated converter with a nonisolated hybrid converter significantly reduces complexity, cost, and board space requirements. For a high input/output voltage application (48 V to 12 V), a conventional buck converter is not an ideal solution because component size tends to be larger.
The DY120-DD48-48 is a 48V converter of 120W. The converter can convert 48V to 48V DC and supply a DC current of 2,5A to 3,1A. The CP200-DD48-C is a DC/DC converter that converts a varying DC voltage from 48V to a stable 48V DC voltage and can provide a DC current of 3,75A.
Among the primary electronic units in the MHEV 48 V system are a three−phase inverter to operate the starter/generator which charges the 48V battery and the DC−DC converter that ties the 12V and 48V power nets together. DC-DC converter can be designed either as unidirectional or bidirectional, where unidirectional function (Step-down) is mandatory.
