1. Purpose

<p class="MsoNormal">The RT7236 is a high-performance 650kHz 5A step down regulator with an internal power switch and synchronous rectifier. This document explains the function and use of the RT7236 evaluation board (EVB) and provides information to enable operation and modification of the evaluation board and circuit to suit individual requirements. </p>

2. Introduction

<h3>General Product Information</h3> <p class="bady">The RT7236 is a high-performance 650kHz 5A step down regulator with an internal power switch and synchronous rectifier. It features quick transient response using its Advanced Constant On-Time (ACOT^TM) control architecture that provides stable operation with small ceramic output capacitors and without complicated external compensation, among other benefits. The input voltage range is from 4.5V to 18V and the output is adjustable from 0.765V to 8V.</p> <p class="bady">The proprietary ACOT^TM control improves upon other fast response constant on-time architectures, achieving nearly constant switching frequency over line, load, and output voltage ranges. Since there is no internal clock, response to transients is nearly instantaneous and inductor current can ramp quickly to maintain output regulation without large bulk output capacitance. The RT7236 is stable with and optimized for ceramic output capacitors.</p> <p class="bady">With its internal 90mΩ switch and 60mΩ synchronous rectifier, the RT7236 displays excellent efficiency and good behavior across a range of applications, especially for low output voltages and low duty cycles. Cycle-by cycle current limit, input under-voltage lock-out, externally-adjustable soft-start, output under- and overvoltage protection, and thermal shutdown provide safe and smooth operation in all operating conditions.</p> <p class="bady">The RT7236 evaluation board uses the RT7236GQW IC in a WDFN-10L 3x3 package with an exposed thermal pad. The IC is also available in a PTSSOP-14 package with an exposed thermal pad.</p> <h3>Product Feature</h3> <ul> <li style="color: rgb(35, 31, 32);">Fast Transient Response</li> <li style="color: rgb(35, 31, 32);">Steady 650kHz Switching Frequency at PWM</li> <li style="color: rgb(35, 31, 32);">5A Output Current</li> <li style="color: rgb(35, 31, 32);">Advanced Constant On-Time (ACOT^TM) Control</li> <li style="color: rgb(35, 31, 32);">Optimized for Ceramic Output Capacitors</li> <li style="color: rgb(35, 31, 32);">4.5V to 18V Input Voltage Range</li> <li style="color: rgb(35, 31, 32);">Internal 90mΩ Switch and 60mΩ Synchronous Rectifier</li> <li style="color: rgb(35, 31, 32);">0.765V to 8V Adjustable Output Voltage</li> <li style="color: rgb(35, 31, 32);">Externally-adjustable, Pre-biased Compatible Soft-Start</li> <li style="color: rgb(35, 31, 32);">Cycle-by-Cycle Current Limit</li> <li style="color: rgb(35, 31, 32);">Output Over- and Under-voltage Shut-down</li> </ul> <h3>Key Performance Summary Table</h3> <div> <table class="MsoNormalTable" style="border: currentColor;

Do not exceed their operating voltage range and consider their voltage coefficient (capacitance vs. bias voltage) and ensure that the capacitance is sufficient to maintain stability and provide sufficient transient response for your application. Installing a small 5pF to 22pF capacitor at C30 (in parallel with R23) may be desirable to improve transient response for higher output voltages. See the RT7236 IC datasheet for more information.</p>
