Detailed Description of Hardware

The MAX77291 EV kit evaluates the MAX77291 IC. The MAX77291 is a high- efficiency, low-quiescent current, step-up DC-DC converter with True Shutdown™ and short-circuit protection. True Shutdown disconnects the output from the input with no forward or reverse current. The MAX77291 EV kit operates over an input range of 1.8V to 5.5V. The EV kit provides resistor-configurable output voltages from 5.5V to 20V. The EV kit comes with the MAX77291ANT+ installed and is configured for a 12V output.
The MAX77291 EV kit provides a jumper JU1 to enable or disable the MAX77291. See Table 1 for JU1 jumper settings.
