The MAX16930/1 are dual buck and single preboost controllers for automotive applications. The datasheet says the following on page 13:
The buck controllers and the preboost can each provide up to 10A output current and are independently controllable.
The controllers are each limited to 10A due to the gate drive capability. The MAX16930/1 has a logic-level gate driver with a maximum gate drive of 4.5V. Getting more than 10A of output current becomes difficult, because it requires a logic-level FET with low enough gate charge and high enough drain current rating. The MAX16930/1 can be used with external gate drivers to increase the output current capability if desired.
