Analog Devices MAX17271 | Demoboard MAX17271EVKIT

Description

The MAX17271 evaluation kit (EV kit) evaluates the MAX17271. The MAX17271 is a 3-output switching regulator that regulates three outputs using a single, small 2.2μH inductor. The MAX17271 includes an I2C interface to configure the output voltages. The MAX17271 EV kit features two independent circuits to evaluate two different IC packages of the MAX17271. Both circuits on the EV kit operates over an input range of 2.7V to 5.5V. Each circuit features an I2C interface to set the three output channels to voltages from 0.8V to 5.175V 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 MAX17271 EV kit includes a graphical user interface (GUI) that provides communication over I2C with an onboard IC. The EV kit comes with the MAX17271ETE+ and the MAX17271ENE+ installed.
