Analog Devices / Maxim Integrated MAX77857 Evaluation Kit

Analog Devices MAX77857 Evaluation Kit is a fully assembled and tested Printed Circuit Board (PCB) that demonstrates the MAX77857 buck-boost converter. This device offers 2.5V to 16V input and adjustable output between 4.5V to 15V using internal feedback resistors or 3V to 15V using external feedback resistors. The MAX77857 Evaluation kit is factory-configured as internal feedback with a default startup output voltage at 5V. The Analog Devices MAX77857 Evaluation Kit features I/O pins to support the I²C serial interface, enable function, and interrupt/power-OK indicator.
