In DDR5 designs, power management ICs are integrated directly onto the memory module. As power density increases, maintaining power stability, efficiency and thermal performance has become a key design challenge. Richtek offers a comprehensive portfolio of power management IC solutions for DDR5 server memory, supporting RDIMM, MRDIMM and CXL memory modules. These solutions address a wide range of memory capacities and data rates, with specifications that meet or exceed JEDEC requirements to support diverse server platforms.</p> <h5 class="font-weight-bold mb-3">Key Advantages:</h5> <ul style="line-height:2;"> <li><b>High accuracy, low noise regulation</b>： <p>By combining the proprietary A²RCOT control architecture with a high accuracy reference and fast compensation loop, output voltage accuracy can be maintained within ±0.75%. Load transients and temperature drift are effectively suppressed, meeting the stringent power accuracy requirements of DDR5 memory.</p> </li> <li><b>High reliability with comprehensive protection</b>： <p>Integrated protection features, include over-voltage overcurrent short circuit and over-temperature protection. Enhanced input pin robustness enables reliable operation under demanding conditions, such as hot plug events and fault scenarios, significantly improving overall system stability.</p> </li> <li><b>High efficiency with effective thermal management</b>： <p>High efficiency synchronous rectification achieves conversion efficiency above 92%. Accurate temperature monitoring and overtemperature protection help reduce power loss and thermal stress across operating conditions.</p> </li> <li><b>Platform compatibility and validation</b>： <p>Richtek DDR5 server memory power solutions have passed Intel AVL qualification and completed system validation with multiple DRAM vendors, ensuring broad platform compatibility and long-term operational stability across server platforms.</p> </li> </ul> </div> <div class="col-md-12 "> <div class="mb-3"> <div class="section-title font-weight-bold mb-30 pb-3">Richtek Server DDR5 PMIC Solution Portfolio</div> </div> </div> <div class="col-md-12"> <div class=" row justify-content-center"> <table class="table " style="width: 800px;"> <thead class="thead-light"> <tr> <th scope="col" style="padding: 5px 5px;width: 16%;">DDR5</th> <th scope="col">Server Low Current</th> <th scope="col">Server High Current</th> <th scope="col">Server Extreme Current</th> <th scope="col">Sever Extreme Current Gen2</th> </tr> </thead> <tbody> <tr> <th scope="row">JEDEC Standard</th> <td>P5010</td> <td>P5000</td> <td>P5020</td> <td>P5030</td> </tr> <tr> <th scope="row">Richtek Solution</th> <td><a href="https://forms.office.com/Pages/ResponsePage.aspx?id=6GOM0O6GNE6h5UQzg3P0seMVen-xb9hAr_ZA0LheCTNUOUJXOTZSRVZNSFlGU0xIMTZJMzRXSk9IRC4u" target="_blank" style="text-decoration: none; color: #37a6d9;font-size: 1.1rem;"> RTQ5119A </a> </td> <td><a href="https://forms.office.com/Pages/ResponsePage.aspx?id=6GOM0O6GNE6h5UQzg3P0seMVen-xb9hAr_ZA0LheCTNUOUJXOTZSRVZNSFlGU0xIMTZJMzRXSk9IRC4u" target="_blank" style="text-decoration: none; color: #37a6d9;font-size: 1.1rem;"> RTQ5150A </a> </td> <td><a href="https://www.richtek.com/RedirectToProduct?specid=RTQ5152&utm_source=Newsletter&utm_medium=RTWWW&utm_campaign=Issue56EN&sc_lang=en" target="_blank" style="text-decoration: none; color: #37a6d9;font-size: 1.1rem;"> RTQ5152 </a> </td> <td><a href="https://forms.office.com/Pages/ResponsePage.aspx?id=6GOM0O6GNE6h5UQzg3P0seMVen-xb9hAr_ZA0LheCTNUOUJXOTZSRVZNSFlGU0xIMTZJMzRXSk9IRC4u" target="_blank" style="text-decoration: none; color: #37a6d9;font-size: 1.1rem;"> RTQ5153 </a> </td> </tr> <tr> <th scope="row">Applications</th> <td>RDIMM</td> <td>RDIMM、CXL MM</td> <td>RDIMM、MRDIMM、CXL MM</td> <td>RDIMM、MRDIMM、CXL MM</td> </tr> </tbody> </table> </div> </div> <div class="col-md-12 mb-40"> <p>With deep expertise in power management and extensive experience in server applications, Richtek delivers DDR5 memory power solutions that combine high accuracy high reliability and high efficiency, supporting the continued evolution of modern server systems.
