Analog Devices / Maxim Integrated MAX17760AEVKIT Converter Evaluation Kit

Analog Devices MAX17760AEVKIT Converter Evaluation Kit provides a proven design to evaluate the MAX17760 high-efficiency, high-voltage, synchronous step-down DC-DC converter in a TDFN package. The evaluation kit generates 5V at load currents up to 300mA from a 7V to 76V input supply. The evaluation kit features a 400kHz switching frequency for optimum efficiency and component size. The evaluation kit features adjustable input under-voltage lockout, adjustable soft-start, adjustable switching frequency, open-drain active-low RESET signal, and external clock synchronization. The ADI MAX17760AEVKIT evaluation kit also provides a good layout example, which is optimized for conducted, radiated EMI, and thermal performance.
