Product Details

The MAX20429 evaluation kit (EV kit) is a fully assembled and tested application circuit for the MAX20429: a high-efficiency independent phase dual 6A low-voltage buck converter. The EV kit is created with automotive grade components and can test each of the outputs to full load. Various test points and jumpers are included for evaluation. The standard EV kit comes with the MAX20429CAFNA/VY+ installed, which is factory configured for a resistor adjustable output voltage. The default EV kit resistor divider is bypassed with an output voltage of 0.6V on both VOUT1 and VOUT2.

APPLICATIONS

  • Secondary Regulator for SoC / MCU Supply
