3. Power-Up Procedure

<h3>Equipment Required</h3> <ul> <li>RT5716 Evaluation Board </li> <li>DC power supply capable of at least 5.5V and 3A</li> <li>Electronic load capable of 1A</li> <li>Function Generator</li> <li>Oscilloscope</li> </ul>

4. Quick Start Procedures

The evaluation board is fully assembled and tested. Follow the steps listed below to verify its functionality. Do not turn on power supplies until all equipment is well-connected. Do not measure the output voltage ripple with a long ground lead on the oscilloscope probe. Instead, touch the probe tip and ground ring directly across the output capacitor. The setup procedures are listed below. 1) Connect JP21 so that the resistor is connected between the RSEL/ MODE pin and GND to set output voltage level. 2) Connect the power supply to VIN and GND pins and the electronic load to the VO and nearest GND pins before power on. 3) Turn on the input power supply and make sure that the input voltage does not exceed 5.5V. 4) Enable/disable the RT5716 by the EN pin. When the EN pin is higher than the threshold voltage of logic-high, the IC operates at normal mode; When the EN pin goes low, the RT5716 enters shutdown mode. In shutdown mode, the converter stops switching, internal control circuitry is turned off and discharge function is triggered. 5) When RT5716 starts up, the RSEL/MODE pin operates as an input used for mode selection. When connecting the RSEL/MODE pin to L, the RT5716 operates at Auto Mode, which is PFM mode; On the other hand, the RT5716 operates at FPWM mode when connecting the RSEL/MODE pin to H. 6) Check the output voltage by a voltmeter. 7) Adjust the load within the operating range and measure the output voltage regulation, ripple voltage, power efficiency and other performances.

9. Typical Applications

<h3>EVB Schematic Diagram</h3> <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt5716p-bba/html-images/image002_en.png"><img border="0" width="685" height="367" id="Picture 4" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt5716p-bba/html-images/image002_en.png" alt="Technical Document Image Preview" /></a> 1. The capacitance of the input and output will influence the input and output voltage ripple, respectively. 2. MLCC capacitance degrades at different DC bias voltage. The smaller package size of MLCC capacitors, the more capacitance degradation there would be under the same test condition.
