Expand functionality in automotive infotainment and cluster systems with TI buck converters and controllers
Today's automotive infotainment and cluster systems inform, entertain, and connect modern drivers. As we look to the future, the amount of functionality within these systems is only expected to increase. This means more processing power within the same physical space. In order to power these next-generation systems, power converters need to excel in two key aspects.
- High output power-to-package size ratio without overheating.
- Minimized conducted and radiated electromagnetic interference.
