Product Details

The MAX77887 evaluation kit (EV kit) is a fully assembled and tested printed circuit board (PCB) that demonstrates the MAX77887 nano power buck-boost converter. The IC has an input range of 1.8V to 5.5V, with a switching current limit of 400mA.

The IC has two hardware control pins, SEL1 and SEL2. The resistor connected at SEL1 (R_SEL1) selects a predefined output voltage level between 1.8V to 5.2V. The resistor at SEL2 (R_SEL2) allows to configure the two different switching current limit levels (ILIM), and 16 input voltage monitoring threshold levels.

The EV kit is compatible with the MAX77887 WLP IC (MAX77887AEWL+T) and equipped with test points and jumpers for testing most of the functionality of the device. There are probing sockets on critical nodes (OUT, LX1, and LX2) for precise measurements.
