Product Details

The MAX17640A/MAX17640B/MAX17640C evaluation kits (EV kits) provide proven designs to evaluate the performance of the MAX17640A/MAX17640B/MAX17640C high-voltage, high-efficiency, synchronous step-down DC-DC converters. The MAX17640A converter operates over a 5V to 48V input range and can deliver up to 400mA at a fixed 3.3V output. The MAX17640B converter operates over a 7V to 60V input range and can deliver up to 400mA at a fixed 5V output. The MAX17640C converter operates over a 15V to 60V input range and can deliver up to 400mA at an adjustable 12V output.

The EV kits feature an adjustable input undervoltage-lockout, open-drain active-low RESET, overcurrent protection, selectable mode of operation, and thermal shutdown. Refer to the MAX17640 converter data sheet for a complete description of the part that should be read in conjunction with this data sheet before operating these EV kits.
