3. Power-up Procedure
<h3>Suggestion Required Equipments</h3> <ul> <li>RT5714 Evaluation Board </li> <li>DC power supply capable of at least 5.5V and 3A</li> <li>Electronic load capable of 3A</li> <li>Function Generator</li> <li>Oscilloscope</li> </ul>
4. Quick Start Procedures
<p class="bady">The Evaluation Board is fully assembled and tested. Follow the steps below to verify board operation. Do not turn on supplies until all connections are made. When measuring the output voltage ripple, care must be taken to avoid a long ground lead on the oscilloscope probe. Measure the output voltage ripple by touching the probe tip and ground ring directly across the last output capacitor. </p>
5. Proper measurement equipment setup and follow the procedure below.
<p class="MsoListParagraph">1) Set output voltage by VSEL pin(L for Output1, H for Output2).</p> <p class="MsoListParagraph">2) With power off, connect the input power supply to VIN and GND pins.</p> <p class="MsoListParagraph">3) With power off, connect the electronic load between the VOUT and nearest GND pins. </p> <p class="MsoListParagraph">4) Turn on the power supply at the input. Make sure that the input voltage does not exceeds 5.5V on the Evaluation Board.</p> <p class="MsoListParagraph">5) Enabled the RT5714 by EN pin. When the EN pin is higher than the threshold of logic-high IC goes to normal operation; When EN pin High transfer Low into shutdown mode, the converter stops switching, internal control circuitry is turned off and trigger discharge function. That discharge function will close after count 10ms (typ.).</p> <p class="MsoListParagraph">6) To verify the output voltage VOUT. If VSEL connect to L, output voltage of the RT5714 measurement is Output-1; If VSEL connect to H, output voltage of the RT5714 measurement is Output-2.</p> <p class="MsoListParagraph">7) Check for the proper output voltage using a voltmeter. </p> <p class="MsoListParagraph">8) Once the proper output voltage is established, adjust the load within the operating ranges and observe the output voltage regulation, ripple voltage, efficiency and other performance.</p>
