Product Details

The MAX20408/MAX20410 evaluation kits (EV kits) provide a proven design to evaluate the MAX20408/ MAX20410/MAX20408E/MAX20410E automotive synchronous buck converters with 10µA quiescent current. The EV kit comes with a MAX20410AFOC/VY+ (400kHz) or MAX20408AFOD/VY+ (2.1MHz) installed, as well as various test points and jumpers for evaluation. The EV kit output voltage is fixed 5V or 3.3V and easily configured to 0.8V to 10V with minimum component changes. The MAX20408E/MAX20410E can be evaluated by replacing the installed IC (U1) in the EV kit.

The EV kit is designed to deliver up to 8A/10A with input voltage 3V to 36V. The output voltage quality can be monitored by observing the PGOOD signal.

Applications

  • Automotive ADAS and other safety critical applications
  • Automotive High Power Sensor Fusion
  • Automotive Infotainment Systems
  • Distributed DC Power Systems
  • Navigation and Radio Head Units
