Product Details

The MAX77847 evaluation kit (EV kit) is a 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 the 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, the 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. MAXUSB_INTERFACE# allows the use of a Windows^® based graphical-user interface (GUI) and a detailed register-based interface to exercise all the features of the IC. The EV kit is compatible with any version of MAX77847 IC (MAX77847BEWL+ is the default version installed on the EV kit).
