<p>The RT7084 is housed in a compact 4mm x 4mm QFN package, combining the MCU, gate driver, and buck converter into a single chip. This integration removes the requirement for a separate buck module, ensuring a stable and reliable power supply for the controller. Its built-in buck converter, based on Richtek's patented ACOT<sup>®</sup> control technology, operates with just an 0806-size inductor. By integrating most external components directly into the chip, the <a href="https://www.richtek.com/RedirectToProduct?specid=RT7084C2M&utm_source=RTWWW&utm_medium=RTWWW&utm_campaign=AN90">RT7084</a> simplifies PCB layout and lowers BOM costs. As shown in Figure 3, it enables PCB designs for 4cm server fans.</p>
