Quick StartFollow this procedure to become familiar with the EV kit.Note: In the following sections, software-related items are identified by bolding. Text in bold and underlined refers to items directly from the EV kit software. Text in italics and underlined refers to items from the Windows operating system.

Required Equipment ● MAX77642 EV Kit ● MAX77642 EV Kit GUI ● Windows-Based PC ● Power Supply ● Ammeter ● DVM ● Micro-USB Cable

Procedure1) Install the GUI software. Visit the product webpage at

http://www.maximintegrated.com/MAX77642evkit and navigate to Design Resources to download the latest version of the EV kit software. Save the EV kit software to a temporary folder and extract the files from the ZIP file.

2) Install EV kit shunts according to Table 1.3) Connect a Micro-B USB cable between the EV kit

USB port labelled “GUI” and the Windows-based PC.4) Apply a 3.7V supply (set for 100mA current limit)

through an ammeter (set for 10mA range) across the VBATT and GND2 terminals of the EV kit. Turn the supply on.

5) Open the GUI and select DeviceConnect in the upper-left corner. Wait for a CONNECTED_DEVICE_LIST window to pop up, and then press the Connect button.

6) Measure the voltages on SBB0, SBB1, SBB2, and LDO with a DMM.

This concludes the Quick Start procedure. During general device evaluation, set the ammeter range to great-er than or equal to 1A to minimize the impact of its series resistance.For more information on the GUI, see the Software section.

Detailed Description of Hardware (or Software)Enable Key OptionsThe MAX77642 features individual hardware enable pins for each of the SIMO outputs and the LDO. These enable pins can be connected to SYSA (to enable the corre-sponding resource) or GND (to disable the corresponding resource) through jumpers in J7, J9, J11, and J12.

Programming the Output VoltagesThe SIMO’s and LDO’s output voltages are programmed by connecting resistors from their corresponding RSEL pins to ground. The EV kit features pre-selected resis-tors which can be tied to RSEL pins through jumpers J2, J3, J5, and J8. Additionally, on-board potentiometers can be used to program the entire output voltage range. Refer to the SIMO Output Voltage Configuration and LDO Output Voltage Configuration sections of the MAX77642/MAX77643 data sheet for more information.

Programming the Inductor Peak Current The SIMO’s inductor peak current is programmed by connecting resistors from RSEL_IPK to ground. Several preselected resistors are placed on the EV kit and can be tied to the RSEL_IPK pin through the jumper J6. A through-hole resistor can be placed in R30 for additional options. See the Inductor Peak Current Setting section of the MAX77642/MAX77643 data sheet for more information.

Electronic LoadThe EV kit comes with an electronic load allowing the user to evaluate the SIMO and LDO load current capabilities. On-board circuits set the load current through the I2C interface. J201, J203, J205, J207 are used to connect the load to the output of the SBB0, SBB1, SBB2, and LDO respectively. To exercise the load transient response, remove J200 (for SBB0), J202 (for SBB1), J204 (for SBB2), and J206 (for LDO), and connect a signal genera-tor to the gate of the load MOSFET (pin 2 of the respective header). Drive the gate with a signal between 1V (off) and 3V (fully on) to apply transients to the output of the SIMO or LDO. Note that there are 0.1Ω sense resistors with test points (called VIL_SBB0, VIL_SBB1, and VIL_SBB2) and a 1Ω sense resistor with a test point (called VIL_LDO) for a 10:1 and 1:1 conversion of load current to voltage. See the Software section to learn how to set the load current from the GUI.

SoftwareThe graphical user interface (GUI) software allows for con-venient, quick, and thorough evaluation of the MAX77642.When the EV kit software detects that a MAX77642 EV kit is connected, only the “Load Control” portion of the GUI can be accessed.

InstallationVisit the product webpage at www.maximintegrated.com/MAX77642evkit and navigate to Design Resources to download the latest version of the EVKit software. Save the EVKit software to a temporary folder and decompress the ZIP file.

Windows DriversUpon connection of a Micro-USB cable between your PC and the EV kit for the first time, wait a few minutes for Windows to automatically install drivers.

Graphical User Interface Details (GUI)The GUI drives I2C communication with the EV kit. Every control in the GUI (excluding the Load Control and ADC/AMUX tabs) corresponds directly to a register within the MAX77642. Hover your cursor over control names for a description of that register. Refer to the IC data sheet for the complete register map.

Load Control TabThe Load Control tab contains controls for load currents on the regulator outputs. The GUI is capable of setting steady-state, transient, and random load currents. To set a load current, use the slider bar or text field to input a value (mA) and check the Enable box. Shuffle through the modes to exercise different load conditions.The offset and gain values are set by Maxim and do not need to be altered.
