See Table 1 for J1 jumper settings. nERR Pin The MAX77720 EV kit provides a jumper J4 to drive the nERR pin as high or low. See Table 1 for J4 jumper settings. www.analog.com Analog Devices | 6 Evaluates: MAX77720 MAX77720 Evaluation Kit Electronic Loads The EV kit comes with an electronic load that allows the user to evaluate the boost and inverting buck-boost load current capabilities. On-board circuits set the load current through I2C (see Table 2). There are two options to exercise load transient response. In the Load Control tab, the GUI offers load transient controls. If faster rise and fall times are required, remove J11 (for IBB), or J10 (for BST) and connect a signal generator to the gate of the load MOSFET (pin 2 of the respective header). Drive the gate with a signal between 1V and 3V to apply transients to the output of the BST or IBB. Note that there is a 0.5 sense resistor for a 1:0.5 conversion of the load current to voltage for the BST and a 2 sense resistor for a 1:0.5 conversion of the load current to voltage. See the EV Kit Software section to learn how to set the load current from the GUI.

Before connecting the MAXUSB_INTERFACE# to the EV kit's MAXUSB_INTERFACE# connector (J5), make sure the MAXUSB_INTERFACE# is configured with the following settings: · SW1 and SW2 to ON position (This enables I2C mode on the MAXUSB_INTERFACE#.) · VL jumper (J5) to 1.8V or 3.3V depending on system requirements (This sets the MAXUSB_INTERFACE#'s VIO voltage.) The MAXUSB_INTERFACE# also includes an onboard LDO that can supply the necessary voltage to VIO. To use the VIO supplied from the MAXUSB_INTEFACE# board, jumper J6 must be installed to position 1-2 (VCC and VIO connected). If the user desires to use a 1.2VIO, connect jumper J6 to position 2-3 (VCC and 1.2V) and ensure jumper J7 is installed. This provides power to the onboard 1.2V LDO to provide 1.2VIO compatibility. Additionally, a level shifter is added for users to still communicate using the MAXUSB_INTERFACE# through I2C. External I2C Bus If the user wishes to connect to the external I2C serial bus and not use the MAXUSB_INTERFACE#, unplug the MAXUSB_INTERFACE# from the EV kit's MAXUSB_INTERFACE# connector (J5). Apply an external I/O supply to the VIO pin or power the VIO pin using the onboard 1.2V rail by connecting jumper J6 to the 2-3 position. Make sure the external I2C serial bus's logic voltage level is compatible with the MAX77720's I/O logic voltage level. Refer to the MAX77720 IC data sheet for the appropriate I/O logic voltage levels. Then connect wires to the SDA, SCL, and GND pins on the EV kit to the external I2C serial bus. Boost Output Voltage Configuration The boost output voltage is configured using an external resistor divider. By selecting the external resistor-divider RTOP and RBOT, the output voltage is configured to the desired value. When the output voltage is regulated, the typical voltage at the FBBST pin is 1.25V. Calculate the value of RTOP (from VFBBST to VOUTBST) for a desired VOUTBST at startup with the following equation: = ( - 1) Where: · VOUTBST is the desired positive output voltage. · VFBBST is the default internal reference voltage at the FBBST pin, 1.25V (typ). For best accuracy, set RBOT to a value smaller than 475k to ensure that the current flowing through it is significantly larger than the FBBST pin bias current. The advantage of using a higher value for RTOP is the reduction of quiescent current for achieving the highest efficiency at light load currents. However, using RTOP values that are lower increases immunity against noise injection. Additionally, using one percent tolerance resistors (or better) is recommended to maintain high output voltage accuracy. High-Temperature Testing The MAX77720 is rated for operation under junction temperatures up to +125°C. Note that not all components on the EV kit are rated for temperatures this high. Some ceramic capacitors experience extra leakage when put under temperatures higher than they are rated for and supply current readings for the IC might be larger than expected. The MAXUSB_INTERFACE# is also not rated for +125°C. Double-check the components on the EV kit if testing at +125°C ambient or junction temperatures. Consider replacing these components if IC operation at +125°C ambient or junction temperature is an important use case. List of components not rated for +125°C: · C1, C3, C2 (Input Capacitors) · C4, C6 (Output Boost Capacitors) · C9, C16, C38, C15, C34, C36 (High Frequency Decoupling Capacitors) · C17, C18, C21, C22 (On-Board LDO Capacitors) www.analog.com Analog Devices | 8 Evaluates: MAX77720 MAX77720 Evaluation Kit Efficiency Measurement The MAX77720 EV kit comes with sense pins for accurately measuring input voltage (INBBS, GNDBBS), output Inverting buck-boost voltage (OUTIBBS, GNDIBBS), and output boost voltage (OUTBSTS, GNDBSTS). See Figure 3 for their locations on the EV kit. For the most accurate efficiency, load regulation, and line regulation measurements, use these sense pins to measure input and output voltages. WARNING: These sense pins are only for measuring voltages, do not connect the input supply to input sense pins, and do not connect the electronic load to output sense pins, as these sense pins are not designed to have current running through them. Doing so damages the EV kit. Use input supply terminals (IN, PGND) and use output terminals (OUTBST, PGNDBST, OUTIBB, and PGNDIBB) for connecting to electronic load as shown in Figure 3. General PCB Layout Guidelines Careful printed circuit board layout is critical to achieving low-switching power losses and a clean stable operation by increasing noise immunity. When laying out the PCB, follow these general guidelines: · Place the inductors and output capacitors of the DC-DC converters close to the MAX77720 and keep the power loop small. · When routing the current path of the DC-DC converters, short and wide traces should be used to reduce any EMI issues radiated from the fast switching. The trace between the LX pin and the inductor is the most critical for this. · The ground loop for the input and output capacitor should be as small as possible. · For multilayer PCBs, the analog ground (AGND) should be on its own plane, and the power ground (PGND) should be on its separate plane. AGND should be directly connected to the ground plane separately, to ensure a quiet ground plane for AGND and to avoid common impedance grounding. · The feedback pins should be routed away from the LX switching node to increase noise immunity. This pin is a highimpedance input that is highly noise sensitive. · When possible, ground planes and traces should be used to help shield the feedback signal and minimize noise and magnetic interference. For multilayer PCBs, a ground plane should be in between the high current paths and any analog or digital paths.

MAX77720 Tab--Delay0 and Delay1 www.analog.com Analog Devices | 14 Evaluates: MAX77720 MAX77720 Evaluation Kit Load Control Tab The Load Control tab contains controls for load current on the regulator's outputs. The GUI is capable of setting steadystate, transients, 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. Note: for the onboard electronic loads to function, jumpers J11 and J13 must be connected to the IBB rail, and jumpers J10 and J12 must be connected to the BST rail. The offset and gain values are set by Analog Devices and do not need to be altered. However, in the case that the load control seems to be inaccurate, make sure the constants match (see Figure 19 and Figure 20) for the IBB and BST load control respectively. For the IBB load control, the electronic load is unable to load up to the maximum load capabilities that the IBB can handle. If the user wishes to add more load current, using an external electronic load or a power resistor is recommended. Figure 19. IBB Load Control Values Figure 20.
