MAX77839QEVKIT#

MAX77839QEVKIT# is a MAX77839 evaluation kit (EV kit). It provides a proven design to evaluate MAX77839, a 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 (with SEL pin). The factory default output voltage of this EV kit is set at 3.3V. Output voltage can be adjusted by changing the SEL resistor value (R3). GPIO pin is available to support force PWM or POK functionality. The EV kit is compatible with any version of the MAX77839 FC2QFN IC (MAX77827AEFQ+ is the default). Typical applications include 5G/2G/GSM cellular power, asset tracking/fleet management, RF amplifier, single-cell Li-ion battery powered devices, smartphones ToF/facial and gesture recognition, system power pre-regulation.
