overview

1. Purpose

<p class="MsoNormal">The RT2613A is a synchronous step-down converter with the input voltage range from 2.95V to 6V and provides 3A output current. This document explains the function and use of the RT2613A evaluation board (EVB), and provides information to enable operation, modification of the evaluation board and circuit to suit individual requirements.</p>

2. Introduction

<h3>General Product Information</h3> <p class="bady">The RT2613A is a high efficiency step-down converter and capable of delivering 3A output current over a wide input voltage range from 2.95V to 6V. The RT2613A provides accurate regulation for a variety of loads with ±3% accuracy. For reducing inductor size, it provides up to 2MHz switching frequency. The efficiency is maximized through the integrated 45mΩ MOSFETs and 550μA typical supply current. Under voltage lockout voltage of the RT2613A is 2.7V, and it also provides external setting by a resistor network on the enable pin. The RT2613A provides protections such as inductor current limit under voltage lockout and thermal shutdown. The over temperature threshold is 145°C. The RT2613A is available in WQFN-16L 3x3 package.</p>

7. Power-up & Measurement Procedure

<p class="MsoListParagraph">1. Apply a 12V nominal input power supply (2.95V < V_IN < 6V) to the VIN and GND terminals.</p> <p class="MsoListParagraph">2. Set the jumper at JP1 to connect terminals 1 and 2, connecting EN to enable operation.</p> <p class="MsoListParagraph">3. Verify the output voltage (approximately 1.8V) between VOUT and GND.</p> <p class="MsoListParagraph">4. Connect an external load up to 3A to the VOUT and GND terminals and verify the output voltage and current.</p>

8. Output Voltage Setting

<p class="MsoNormal">Set the output voltage with the resistive divider (R1, R2) between VOUT and GND with the midpoint connected to FB. The output is set by the following formula :</p> <p class="MsoNormal"><a href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt2613agqw/html-images/image003_en.png" class="fancybox"><img width="152" height="36" width="152" height="36" style="border-width: 0px; border-style: solid;" alt="Technical Document Image Preview" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt2613agqw/html-images/image003_en.png" /></a></p>
