MAX77847EVKIT#

MAX77847EVKIT# is an evaluation kit (EV kit) that is fully assembled and tested printed circuit board (PCB) that demonstrates the capabilities of MAX77847 in the Wafer-Level Packaging (WLP) package. It is a highly efficient high-performance buck-boost regulator with a switching current limit of 4.5A/3.6A and an industry-leading quiescent current of 14µA for battery-powered applications. The IC supports an input voltage range from 1.8V to 5.5V and an output voltage range from 1.8V to 5.2V. The output voltage can be set using the SEL pin, and dynamic voltage scaling can be achieved using GPI pin without using the I2C interface. The I2C interface is optional. However, it allows changing the output voltage dynamically in 50mV steps. In addition, I2C interface also allows selecting the switching current limit, ramp-up/ramp-down slew rate, Forced PWM mode operation (FPWM) operation, and monitoring protection status for overcurrent, overvoltage, and thermal shutdown protection for the part.
