Product Details

The MAX20057 evaluation kit (EV kit) is a fully assembled and tested application circuit that simplifies the evaluation of the MAX20057 400kHz/2.1MHz, 36V boost controller and dual buck converters. All installed components are rated for the automotive temperature range. Various test points and jumpers are included for evaluation.

The standard EV kit comes with the MAX20057ATIE/VY+ installed (5V, 3.3V, 2.1MHz), but can also be used to evaluate other MAX20057 variants with minimal component changes shown in the MAX20057 EV Kit Bill of Materials.

Applications

  • Automotive Start-Stop System
  • Distributed DC Power Systems
  • Instrument Cluster
  • Navigation and Radio Head Units
