The Evaluation Board demonstrates the RTQ6360GSP to be designed for a 5V/0.5A output from a 8V to 60V input at 500kHz switching frequency. The wide input range makes it suitable for communications and industrial 12V, 24V and 48V power systems. The RTQ6360GSP provides complete protection functions such as input under-voltage lockout, output under-voltage protection, over-current protection and thermal shut down. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up.

3. Power-up Procedure

<h3>Suggestion Required Equipments</h3> <ul> <li>RTQ6360GSP Evaluation Board </li> <li>DC power supply capable of at least 60V and 1A</li> <li>Electronic load capable of 6A</li> <li>Function Generator</li> <li>Oscilloscope</li> </ul>

4. Quick Start Procedures

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.

5. Proper measurement equipment setup and follow the procedure below.

1) With power off, connect the input power supply to VIN and GND pins. 2) With power off, connect the electronic load between the VOUT and nearest GND pins. 3) Turn on the power supply at the input. Make sure that the input voltage does not exceeds 60V on the Evaluation Board. 4) Check for the proper output voltage using a voltmeter. 5) 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.

9. Typical Applications

<h3>EVB Schematic Diagram </h3> <a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6360gsp/html-images/image002_en.png"><img border="0" width="681" height="259" id="圖片 23" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rtq6360gsp/html-images/image002_en.png" alt="Technical Document Image Preview" /></a> 1. The capacitance values of the input and output capacitors will influence the input and output voltage ripple. 2. MLCC capacitors have degrading capacitance at DC bias voltage, and especially smaller size MLCC capacitors will have much lower capacitance.
