overview

1. General Description

<p class="bady">The RT8577A is an 4-CH LED driver capable of delivering 200mA for each channel. The RT8577A is a current mode boost converter with an adjustable switching frequency via the RT pin from 200kHz to 2.1MHz and a wide VIN range from 5V to 40V.</p>

3. Power-up Procedure

<h3>Suggestion Required Equipments</h3> <ul> <li>RT8577A Evaluation Board </li> <li>DC power supply capable of at least 12V and 10A</li> <li>LED Load Board</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) With power off, connect the power supply for VIN and GND pins.</p> <p class="MsoListParagraph">2) With power off, use jumper to pull high for EN pin.</p> <p class="MsoListParagraph">3) With power off, connect the Function Generator to PWM pin.</p> <p class="MsoListParagraph">4) With power off, connect the LED Load Board to VOUT and LEDx pins. </p> <p class="MsoListParagraph">5) Turn on the power supply at the input. Make sure that the input voltage does not exceeds 24V on the Evaluation Board.</p> <p class="MsoListParagraph">6) Turn on the Function Generator at the PWM pin.</p> <p class="MsoListParagraph">7) Check LED Load Board brightness.</p> <p class="MsoListParagraph">8) Once the proper output voltage is established, adjust the PWM duty within the operating ranges and observe the output LED brightness , I_LEDx , efficiency and other performance.</p>
