overview

1. Purpose

<p class="MsoNormal">The RT7249 is a current mode step-down converter with the input voltage range from 4.5V to 18V and provides 3A outputcurrent. This document explains the function and use of the RT7249 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 RT7249 is a high efficiency, monolithic synchronous step-down DC/DC converter with a power switch.The buck converter can deliver up to 3A output current from 4.5V to 18V input supply. The RT7249’s current-mode architecture and external compensation allow the transient response to be optimized over a wide input range and loads. Cycle-by-cycle current limit provides protection against shorted output and soft-start eliminates input current surge during start-up. The RT7249 also provides under-voltage protection and thermal shutdown. PWM frequency is adjustable by the ROSC pin and Power Switch current limit can also be adjusted by the RLIM pin. The low current (<3µA) in shutdown mode provides output disconnection, enabling easy power management in bettery-powered systems. The RT7249 is available in the WQFN-16L 4x4 package.</p>

7. Power-up & Measurement Procedure

<p class="MsoListParagraph">1. Set the jumper at JP1 to connect terminals 1 and 2, connecting Vout to SW_IN </p> <p class="MsoListParagraph">2. Apply a 12V nominal input power supply to the VIN and GND terminals.</p> <p class="MsoListParagraph">3. Connect an external load up to 6A 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 External Input and GND with the midpoint connected to VREFIN. The output is set by the following formula :</p> <p class="MsoNormal"><a href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt7249gqw/html-images/image002_en.png" class="fancybox"><img width="143" height="48" width="143" height="48" alt="Technical Document Image Preview" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt7249gqw/html-images/image002_en.png" /></a></p>
