The MAX17559 EV kit is a proven design to evaluate the dual synchronous step-down regulator that provides independent 3.3V and 5V outputs capable of driving 8A and 15A loads from the 6V to 60V input-voltage range. Operating the two regulators 180° out-of-phase significantly reduces the peak input ripple current, allowing the use of smaller, less expensive components, while minimizing parts count. The EV kit features adjustable input undervoltage lockout, soft-start/stop time, and current-limit threshold, as well as selectable PWM/DCM modes, foldback/latchoff current limit, and independent open-drain PGOOD signals. By disabling channel 2, the evaluation kit is capable of operating from a lower input supply (4.5V to 60V), providing a single 3.3V output driving up to 15A.
