Analog Devices / Maxim Integrated MAX77839 Evaluation Kits

Analog Devices MAX77839 Evaluation Kits are used to evaluate the MAX77839 2.5A buck-boost converter. The IC is capable of 1.8V to 5.5V input and is output voltage adjustable between 2.3V to 5.3V (through the SEL pin). The factory default output voltage of the kit is set at 3.3V. Output voltage can be adjusted by changing the SEL resistor value (R3). The GPIO pin is available to support the force PWM or power-OK (POK) function. Analog Devices MAX77839 Evaluation Kits are compatible with any version of the MAX77839 WLP IC (MAX77839AEWC+ is the default).
