1 / 23 page  Evaluates: MAX20343/MAX20344 MAX20343 Evaluation Kit General Description The MAX20343 evaluation kit (EV kit) is a fully assembled and tested circuit that evaluates the MAX20343/MAX20344 3.5W, buck-boost regulator. The MAX20343 is designed for low-noise, battery-powered applications that require long runtimes. The EV kit is compatible with both the I2C controlled and single-pin-enabled versions of the MAX20343/MAX20344. Refer to the MAX20343/MAX20344 IC data sheet for detailed information regarding the operation and features of the device. Features ● RoHS Compliant ● Proven PCB Layout ● Fully Assembled and Tested ● USB Controllable for I2C Configured Devices 319-100335; Rev 1; 12/20 Ordering Information appears at end of data sheet. Quick Start Required Equipment The following equipment is required to verify the function- ality of this EV kit. The list assumes the EV kit is used with the I2C-controlled version of MAX20343. ● USB-A to Micro-USB Cable ● Host PC with One USB Port and the MAX20343 Evaluation Kit Tool Installed ● Adjustable Power Supply with 5.5V Capability ● Voltmeter Optional Equipment The following equipment can be used for more complete evaluation of the EV kit: ● Two (2) Ammeters ● Load (Electronic or Passive) Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation when using the I2C controlled version of MAX20343: 1) Install the MAX20343 Evaluation Kit Tool on the host PC. 2) Connect the USB cable from the host PC to the MAX20343EVKIT and run the GUI. 3) Verify that the shunt jumpers are installed in their default positions. 4) Set the voltage on the power supply to 3.3V, then connect the positive terminal to VIN and the com- mon/negative terminal to GND. 5) Verify that the GUI has detected and connected to the EV kit and that LED D5 on the EV kit is illuminated. 6) On the General tab of the GUI, uncheck the boxes for Output Voltage Interrupt Mask and Input UVLO Interrupt Mask. 7) Press the Read button to read the interrupt states. Verify that LED D2 is off. 8) Switch to the Buck-Boost tab of the GUI and verify that the Output Voltage slider is set to 5.5V, then enable the regulator using the Buck-Boost Enable radio button. 9) Verify that LED D2 is illuminated.
