RT8800A是一通用型多相同步降压转换器，适合高功率密度应用，可在自动的错相设定中执行2或3同步降压转换阶段。此多相架构让供电应用在高输出电流中，可维持低功耗和输入、输出电容的低应力。输出电压透过PI接脚的外部参考电压精确调节，当配合DAC发生器RT9401A/B，即可提供Intel<SUP>®</SUP> VRD10.x 或AMD<SUP>®</SUP> K8标准输出电压。RT8800A采用创新的时分 DCR 电流检测技术实施电流平衡操作、降压调整和过流保护，并用检测电流的通用GM放大器消除偏移误差及GM间的线性不一致性。由于现代的主机板普遍使用了低于毫欧姆级的电感，小的偏移和线性不一致性即可导致可观的相间电流不平衡，这让时分DCR技术更加重要，确保大规模量产中的电流平衡效果。RT8800A 的设计中还包含了多种其它特性，如过压保护、欠压保护和内部软起动等。其封装为 VQFN-16L 3x3。
