As automotive designers are tasked with adding more features to modern, high-end cars, the number of power rails continue to increase as well. Each individual power rail is powered from the car battery through a front-end buck converter. Designers need a highly efficient, compact solution that meets or exceeds electromagnetic interference (EMI) requirements. On top of all those challenges, they need to meet stringent safety standards in the industry.

Compact buck converters claiming the lowest EMI

The new MAX20073 and MAX20074 buck converters from Maxim Integrated are designed to meet all these prerequisites for automotive designers. The compact converters claim the lowest EMI in the industry, reducing interference that can impact the function of sub-systems in a small solution size with ultra-low quiescent current. They are ideal for low-voltage point-of-load applications, automotive infotainment and ADAS applications.

Key advantages:

  • Lowest EMI: Mitigate the system EMI radiation easing the effort for designers to meet EMI specifications
  • Higher Efficiency: Exhibits superior efficiency across the entire operating range
  • Small Solution Size: Its small 3mm x 3mm 10-pin TDFN-EP package reduces overall system footprint, while saving system BOM cost
  • Output Voltage Accuracy: Output voltage can be pre-set at the factory to allow ±1.5 percent output-voltage accuracy without the need for expensive 0.1 percent external resistors

Availability and Pricing:

The MAX20073 is available for $1.20 and MAX20074 is available for $1.30. They operate over the -40-degree Celsius to +125-degree Celsius ambient temperature range.
