Product Details

The MAX17558 EV kit provides a proven design to evaluate the MAX17558 wide 4.5V to 60V input, dual-output, synchronous step-down DC-DC controller. The EV kit provides 5V/5A and 3.3V/10A at the outputs from a 6V to 60V input supply. The switching frequency of the EV kit is preset to 350kHz for optimal efficiency and component size. The EV kit features adjustable input undervoltage-lockout and soft-start time, selectable PWM/DCM modes, 180° out-of-phase/0° in-phase operation, current-limit threshold, and independent open-drain PGOOD signals.
