产品详情
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 at 400kHz switching frequency over a 6.5V to 36V input voltage range and deliver up to 10A load current.
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.
