overview

1. Purpose

<p class="MsoNormal">The RT2825 is a current mode step-down converter with the input voltage range from 4.5V to 18V and provides two channels 5A output current. This document explains the function and use of the RT2825 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 RT2825 features two synchronous wide input range high efficiency buck converters that can deliver up to 5A output current from a 4.5V to 18V input supply. The converters are designed to simplify its application while giving the designer the option to optimize their usage according to the target application. </p> <p class="bady">The converters can operate in 5V, 9V, 12V or 15V systems and have integrated power transistors. The RT2825's current mode architecture allows the transient response to be improved. Cycle-by-cycle current limit provides protection against shorted outputs. </p> <p class="bady">Each converter features enable pin that allows a delayed start-up for sequencing purposes, soft-start pin that allows adjustable soft-start time by choosing the soft-start capacitor, and a current limit (RLIMx) pin that enables designer to adjust current limit by selecting an external resistor and optimize the choice of inductor. The COMP pin allows optimizing transient versus dc accuracy response with a simple RC compensation. </p> <p class="bady">The switching frequency of the converters can either be set with an external resistor connected to ROSC pin or can be synchronized to an external clock if needed. The switching regulators are designed to operate from 200kHz to 1MHz. The converters operate with 180°<span lang="EN-US" style="font-family:Symbol"> </span>phase between two channels to minimize the input filter requirements. </p> <p class="bady">The RT2825 also features a low power mode enabled by an external signal, which allows for a reduction on the input power supplied to the system when the host processor is in stand-by (low activity) mode. </p> <p class="bady">The RT2825 is available in a VQFN-36L 6x6 package.</p>

7. Power-up & Measurement Procedure

<p class="MsoListParagraph">1. Connect input power (4.5V < V_IN < 18V) and input ground to VIN12 and GND respectively.</p> <p class="MsoListParagraph">2. Connect positive end and negative terminals of load to VOUT1/VOUT2 and VOUT1_PGND/VOUT2_PGND respectively.</p> <p class="MsoListParagraph">3. There is a 3-pin header “EN” for enable control. To use a jumper at “H” option to tie EN test pin to input power VIN via a 100k resistor for enabling the device. Inversely, to use a jumper at “L” option to tie EN test pin and ground GND for disabling the device. Let EN floating will also enable control.</p> <p class="MsoListParagraph">4. Verify the output voltage (approximately 1.8V) between VOUT1/VOUT2 and GND.</p> <p class="MsoListParagraph">5. Connect an external load up to 5A to the VOUT1/VOUT2 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 (R_UP = R7, R8; R_DOWN = R6, R9) between VOUT and GND with the midpoint connected to FB. The output is set by the following formula :</p> <p class="MsoNormal"><a name="_Toc409666845"><a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt2825gqv(2)/html-images/image002_en.png"><img border="0" width="190" height="50" id="圖片 1" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt2825gqv(2)/html-images/image002_en.png" alt="一張含有 字型, 文字, 行, 數字 的圖片 自動產生的描述" /></a></a></p>

9. Frequency Setting

<p class="MsoNormal">Set the converter frequency with the oscilator resistor (R_OSC = R11) between OSC and GND. The practical switching frequency ranges from 200kHz to 1MHz. Determine the R_OSC resistor value by examining the curve in below Figure.</p> <p class="MsoNormal"><a class="fancybox" href="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt2825gqv(2)/html-images/image003_en.jpg"><img border="0" width="317" height="250" id="圖片 21" src="/content/dam/richtek-eds/resources/evaluation-boards/evb_rt2825gqv(2)/html-images/image003_en.jpg" alt="Technical Document Image Preview" /></a></p>
