3. Power-up Procedure

<h3>Suggestion Required Equipments</h3> <ul> <li>DC Power Supply (Chroma, 62006P-100-25)</li> <li>Electronic load capable of 6A</li> <li>DC Meter</li> <li>Richtek Wrenboard</li> </ul>

4. Quick Start Procedures

<p class="MsoListParagraph">1. Apply V_S = 3.3V input power supply (2.7V < V_S < 5.5V) to VS and GND terminals.</p> <p class="MsoListParagraph">2. Apply 12V input power voltage (0V < IN+ < 36V) to IN+ and GND terminals.</p> <p class="MsoListParagraph">3. The default sense resistance is 100mΩ.</p> <p class="MsoListParagraph">4. Connect an external load to IN- and GND terminals, and keep loading current = 0.5A.</p> <p class="MsoListParagraph">5. Measure the sense voltage (approximately 50mV) between IN+ and IN-.</p> <p class="MsoListParagraph">6. Use RTQ6056 GUI to check practical sense voltage, bus voltage, current and power.</p>

5. Graphical User Interface

RTQ6056 Graphical User Interface</p>

6. Configuring the RTQ6056 EVB Software

<p class="MsoNormal">Step 1. Set the shunt resistor value.</p> <p class="MsoNormal">Step 2. Set Max expected current for sensing.</p> <p class="MsoNormal">Step 3. Set minimum current resolution for current LSB.</p> <p class="MsoNormal">Step 4. Push “Apply” bottom, the 0x05 Calibration register is written into a value for expected current LSB. </p> <p class="MsoNormal">Step 5. Select single read or continued read for showing practical data. </p>

7. Alert Indicator

<p class="bady">Figure 2 shows an example for configuring the Alert pin. The user can monitor five alert functions or conversion ready notification through the alert config drop-down menu, and the threshold can be programed in the Alert Limit.</p> <p class="bady">The five alert functions are listed below:</p> <ul> <li>Sense Voltage Over-Limit (SOL) </li> <li>Sense Voltage Under-Limit (SUL) </li> <li>Bus Voltage Over-Limit (BOL)</li> <li>Bus Voltage Under-Limit (BUL) </li> <li>Power Over-Limit (POL)</li> </ul> <p class="MsoNormal"><a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6056gf/html-images/image002_en.jpg"><img width="180" height="85" id="圖片 25" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6056gf/html-images/image002_en.jpg" alt="Technical Document Image Preview" /></a></p> <p class="MsoNormal">Figure 2.
