Description

The MAX17250 TDFN EV kit evaluates the MAX17250 IC in a TDFN package. The MAX17250 are high-efficiency, low quiescent current synchronous step-up DC-DC converters with True Shutdown, programmable input current limit and short-circuit protection. The MAX17250 TDFN EV kit operates over an input range of 2.7V to 18V, depending on load. The EV kit provides resistor-configurable output voltages from 3V to 18V. The inductor peak current limit can be set to 3.5A/2.7A/1.85A. The EV Kit comes with the MAX17250ATD+ (TDFN) installed and is configured for a 12V output. The 12V output can deliver 720mA of current at 6V input.
