Overview

TopologyBuck Converter
Input voltage6.5-80 V
Output 15 V / 3 A

Description

The MAX17793 5V output evaluation board provides a proven design to evaluate the MAX17793 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 80V input voltage range and deliver up to 3A 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 MAX17793 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.
