Analog Devices Inc. MAX77837 Evaluation Kit is a fully assembled and tested printed circuit board (PCB) demonstrating the WLP-packaged MAX77837 nanoPower Buck-Boost Converter. The kit features an input range of 1.8V to 5.5V and a switch current limit of 1.05A. The kit is equipped with test points and jumpers to test the converter’s functionality. In addition, there are probing sockets on critical nodes (OUT-1, LX1, and LX2) for precise measurements.
The ADI MAX77837 IC offers two unique hardware control pins, SEL1 and SEL2. The resistor connected at SEL1 (RSEL1) selects a predefined combination of two output voltages between 1.8V to 5.2V, OUT1 and OUT2. The resistor connected at SEL2 (RSEL2) allows different configurations of switch current limit to optimize external component size, enable or disable DVS function, select either hiccup or latch-off mode, and IC startup voltage.
