MAX17231EVKIT#

The MAX17231EVKIT# is an evaluation kit (EV kit) for MAX17231. It is a fully assembled and tested application circuit board for the MAX17231 high-voltage, dual synchronous step-down controller with preboost. The EV kit is set up to provide 5V and 3.3V from an input voltage ranging from 3.5V to 36V. The preboost circuit maintains the 10V supply rail for input voltages below 10V. Each buck rail can deliver up to 5A load current. Various jumpers are provided to help evaluate features of the MAX17231 IC. Typical applications include distributed supply regulation, general-purpose point-of-load and wall transformer regulation.

• Dual, synchronous step-down controllers operate at 180° out-of-phase to reduce switching noise
• Preboost controller to maintain operation with low supply voltage
• Current-mode controllers with forced-PWM and skip modes
• Resistor-configurable frequency between 1MHz and 2.2MHz
• Independent enable inputs
• 85% peak efficiency at 12V input in skip-mode
• FSYNC input and power good output
• Proven 4-layer 2oz copper PCB layout
• Demonstrates 1937mil x 1702mil solution size
• Fully assembled and tested
