ANALOG DEVICES MAX77837WEVKIT# Evaluation Board, MAX77837EWA+T, Power Management - Voltage Regulator, Buck/Boost Converter

MAX77837WEVKIT# evaluation kit (EV kit) evaluates MAX77837 in WLP package. It is a fully assembled and tested printed circuit board (PCB) that demonstrating the MAX77837 nano power buck-boost converter. The EV kit has an input range of 1.8V to 5.5V, with a switch current limit of 1.05A. The MAX77837 IC has two hardware control pins, SEL1 and SEL2. The resistor connected at SEL1 (RSEL1) selects a predefined combination of two output voltages between 1.8V and 5.2V, OUT1 and OUT2. The resistor connected at SEL2 (RSEL2) allows different configurations of switch current limit to optimize external components size, enable or disable DVS function, select either hiccup or latch-off mode, and IC startup voltage. The EV kit is compatible with MAX77837 WLP IC (MAX77837EWA+T) and equipped with test points and jumpers to test most of the device's functionality. In addition, there are probing sockets on critical nodes (OUT-1, LX1, and LX2) for precise measurements.

• Accessible test points for INS and OUTS
• Output voltage (OUT1 and OUT2) adjustable using RSEL1
• Switch current limit, DVS function, and hiccup or latch off mode operation
• Sense sockets for high-accuracy measurements
• 1.8V to 5.2V output voltage (configured using RSEL1 and RSEL2)
• 10nA typical shutdown supply current (EN = LOW, TJ = +25°C)
• 430nA typical input quiescent current (EN = HIGH, TJ = +25°C, and no switching)
