MAX17639EVKITA

Product Details

The MAX17639 5V output evaluation board provides a proven design to evaluate the MAX17639 high-voltage, high-efficiency, synchronous step-down DC-DC converters. The application circuit is configured to demonstrate optimum performance and component sizes in the evaluation board. The evaluation board also provides a good layout example, optimized for conducted, radiated electromagnetic interference (EMI), and thermal performance.

The evaluation board is configured to operate with the MAX17639 device at 400kHz switching frequency over a 6.5V to 36V input voltage range and can deliver up to 10A load current. The evaluation board can also be used to evaluate the MAX17636 and MAX17638 devices. Refer to the IC data sheet for guidance when modifying the schematic.

The evaluation board features an adjustable input undervoltage-lockout, adjustable soft-start, open-drain RESET/TJ, die temperature monitor, external clock synchronization, thermal shutdown, and selectable mode of operation [pulse-width modulation (PWM) or switching frequency modulation (SFM)].

The MAX17639 converter data sheet provides a complete description of the part that should be read in conjunction with this user guide before operating the evaluation board.
