Beschreibung

The MAX17270 evaluation kit (EV kit) evaluates the MAX17270. The MAX17270 is a 3-output switching regulator that regulates three outputs using a single, small 2.2μH inductor. The MAX17270 EV kit features two independent circuits to evaluate two different IC packages of the MAX17270. Both circuits on the EV kit operates over an input range of 2.7V to 5.5V. Each circuit provides three jumper configurable outputs, with voltages from 0.8V to 5V for each output channel. Each circuit output on the EV kit delivers up to 50mA/75mA/80mA of current depending on the input voltage to the output voltage ratio. The EV kit comes with the MAX17270ETE+ and the MAX17270ENE+ installed.
