Product Details

The MAX20059 EV kit is a proven design to evaluate the MAX20059 high-efficiency, high-voltage, synchronous step-down DC-DC converter IC in a TDFN package. The EV kit is optimized to generate a 5V output at load currents up to 1A from a 48V input supply, and can be reconfigured to meet other system requirements. The EV kit features a 400kHz switching frequency. The EV kit can be used to monitor the IC’s features, such as adjustable input undervoltage lockout, adjustable soft-start, adjustable switching frequency, adjustable current limit, open-drain active-low RESET signal, and external frequency synchronization.
