To start the MAX16826 EV kit software, click Start | Programs | Maxim MAX16826 Evaluation Kit | Maxim MAX16826 Evaluation Kit that is created during installation. The GUI main window appears as shown in Figure 1.Figure 1. MAX16826 EV Kit Software Main WindowString Current SetThe String Current Set group box is located at the upperleft corner of the main window. Use the scrollbars toadjust the current of the LED strings. The correspondingvalues of the current will be shown in the adjacent editboxes. Press the Read button to read the values from thelinear regulator output registers of the MAX16826. Theequivalent values of the output current will be shown inthe edit boxes.Boost Output ControlThe Boost Output Control Mode group box has thefunctions to control the boost output voltage.To control the boost output voltage manually, click on theradio button next to the Manual Control group box. Usethe scrollbar to adjust the output voltage, and the volt-age value will be displayed in the adjacent edit box. Theactual boost output voltage can be seen in the Read BackValues group box.To use the software automatic control, click on the radiobutton next to the Software Control group box. The editbox next to the Set button is used to change the Drain toGND regulated voltage of the current sink FETs on the LEDstring with the highest voltage drop. This voltage setting willdepend on how much overhead the user is willing to have.If the set value is too low, the LED currents will no longerbe well regulated and may indeed drop because the boostvoltage might fall too low. The scrollbar in this mode willmove automatically to compensate and regulate the outputvoltage. The update rate is approximately once per second.In any case, the channel with the lowest voltage across thesink FET will be regulated to the value in the edit box. DIM Pulse Width Modulation (DPWM)The DPWM group box is located at the center of the mainwindow. The four DIM PWM signals generated by theon-board MAXQ2000 microcontrollers are used to controlthe brightness of the LEDs. Adjust the scrollbars in theDPWM Duty Cycle group box to change the duty cycles of the PWM signals and the values of the duty cycle (%)are shown in the adjacent edit boxes. Check the Set AllChannels to 100% Duty Cycle checkbox to force all channel duty cycles to 100%.In the DPWM Frequency group box, change the DPWMfrequency by adjusting the scrollbar position and pressthe Set button. The frequency value will be shown in theedit box.To guarantee that the leading edge of all the DIM signalsare synchronized, press the Set button in the DPWMFrequency group box.Press the Start button to start to generate the PWM signals.Press the Stop button to stop all PWM signals.StatusThe Status group box is located at the right of the main window. The software reads the external FET drain voltage measurements, and the boost output voltage measurement from the ADC output registers of the MAX16826. The software multiplies the measured values by the appropriate scaling factor and then displays them in the Read Back Values group box.Enter the values into the edit boxes in the Fault Level Set group box to set the fault-detection values. When the value in the Read Back Values group box is less than the fault-detection value, then the color of the read-back value changes to dark green. When the read-back value is 0 to 10% higher than the fault-detection value, the read-back value turns a lime color. If the read-back value is more than 10% higher than the fault-detection value, then the read-back value turns purple. The read-back value turns red when it is more than 20% higher than the fault-detection value.The software also reads the fault register to detect the fault conditions. If a fault condition exists, it will be shown in the String Fault Status group box. See Table 2 for the fault-condition explanations.Press the Read button to update the Status group box. By checking the Automatic Read checkbox, the Status group box will be automatically updated every second. Enable/DisableThe Enable/Disable group box controls the signal on the SYNC/EN pin. Click on the Enable radio button to set the signal high and enable the MAX16826. Click on the Disable radio button to set the signal low and disable the MAX16826.StandbyCheck the Standby checkbox to set the MAX16826 to standby mode. Refer to the MAX16826 IC data sheet for more information regarding standby mode.Table 2. Fault Conditions*Open LED string detection may require multiple flag examination. FAULT NAME CONDITIONTOADC conversion timeout; alsocorresponds to open string condition* Open LED string openShort LED string shortedOVP OvervoltageScaling FactorsThe calculations for the LED string current, boost output voltage, and the read-back values are based on the scal-ing factors. You can change the scaling factor by select-ing the Scaling Factor menu item under the Scaling Factors menu bar. In the pop-up window shown in Figure 2, enter the appropriate scaling factor.See Table 3 for the formulas for the scaling factors. These values can be used for calibration against actual read values with external instruments.When the default values are changed, they are stored in the software. Re-enter the default values to bring the software back to the default setting.Table 3. Scaling FactorFigure 2.

This EV kit consists of a controller board and an LED driver board. The break-away slots at the center of the EV kit make it easier for the user to break and separate the controller board from the LED driver board. This is done so that once the evaluation is complete with the included software, the driver board can easily be used in the target application environment with the target system microcontroller.To connect the power, ground, PWM, and the I2C inter-face signals of the boards, attach the ribbon cable to the P1 connector of the controller board and attach the other end of the ribbon cable to the P2 connector of the LED driver board.Controller BoardThe controller board acts as the bridge between the soft-ware in the PC and the actual LED driver board containing the MAX16826. In addition to the USB connectivity, it gen-erates the four adjustable PWM DIM signals that control the brightness of the LEDs. The controller board com-municates with the driver board through the I2C interface, and is able to read or change the values of the registers in the MAX16826.The user can use the MAX16826 evaluation kit software to control the controller board.See Table 1 to control the MAX16826 with a user-supplied PWM signal.LED Driver BoardThe LED driver board is able to drive up to four LED strings (7 LEDs/string). LED strings can be connected to the LED driver board through the P3 connector by using a ribbon cable. Connect all of the anode ends of the LED strings to the P3-1 pin (which connects to the boost out-put) of the P3 connector. Then connect the cathode ends of the LED strings to the P3-2 to P3-5 pins (that connects to the drains of the sink FETs) of the P3 connector. User-Supplied I2C InterfaceTo use the MAX16826 EV kit with a user-supplied I2C interface, install the shunts on pins 2-3 of JU4 and JU5. Connect SDA, SCL, and GND lines from the usersupplied I2C interface to the SDA, SCL, and PGND pads on the MAX16826 controller board.After the LED driver board has broken away from the controller board, the user may connect their supplied I2C, DIM, and power signals to the LED driver board through the P2 connector using a ribbon cable. See Table 4 for the pin description of the P2 connector.Table 4.
