Product Details

The MAX77827 evaluation kit (EV kit) provides a proven design to evaluate the MAX77827, a 1.6A buck-boost converter. The IC is capable of 1.8V to 5.5V input and is output voltage adjustable between 2.3 to 5.3V (through 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). Two GPIO pins are available to support Force PWM and EN functions. The EV kit is compatible with any version of the MAX77827 WLP IC (MAX77827CEWC+ is the default).
