Product Details

The MAX77348 evaluation kit (EV kit) provides a proven design to evaluate the MAX77348, a 3.5 W buck-boost converter. The IC is capable of 2.3 V to 5.5 V input, and its output voltage is adjustable between 2.5 V to 4.8 V. The factory default output voltage of this EV kit is set at 4.5 V. Output voltage can be adjusted through the software GUI. The EN pin supports hardware or software enabling of the device. The EV kit is compatible with any version of the MAX77348 WLP IC (MAX77348AEWE+ is the default).
