MAX17233EVKIT#

The MAX17233EVKIT# is a fully assembled and tested application circuit board for MAX17233 high voltage, dual synchronous step down controller with integrated MOSFET. This IC operates over a 3.5V to 36V input voltage range with 42V input transient protection and can operate in dropout condition by running at 95% duty cycle. The evaluation kit is set up to provide 5V and 3.3V from an input voltage ranging from 6V to 36V. Each buck rail can deliver up to 5A load current. The switching frequency is set at 2.2MHz for both buck converters. Various jumpers are provided to help evaluate features of the MAX17233 IC. The MAX17233 EV kit can be modified to operate the MAX17232. The MAX17232 operates at a switching frequency of 400KHz.

• Dual, synchronous step-down controller operates at 180° out-of-phase to reduce sitching noise
