RTQ8826 是一款 6/5/4/3/2/1 相同步降压控制器。RTQ8826 采用 G-NAVP<sup>TM</sup> (Green Native AVP)，这是立锜专有的拓扑，由 EA 放大器的有限 DC 增益搭配电流模式控制所衍生，使其可轻松设置 droop，以支持所有 CPU / 微处理器对 AVP (Adaptive Voltage Positioning) 的要求。基于 G-NAVP<sup>TM</sup> 拓扑，RTQ8826 具备新一代快速响应机制 (Adaptive Quick Response, AQR)，可在负载瞬态期间优化 AVP 性能并减少输出电容。RTQ8826 支持 VID on-the-fly 功能，可通过 PMBus 命令设置四种不同的压摆率。DAC 可将 VOUT_COMMAND 码转换为 0.25V 至 1.516V 的范围，步进为每阶 1.953mV。RTQ8826 集成高精度 ADC，用于平台与功能设置，例如 SPS 类型、PMBus 地址、启动电压与负载线。RTQ8826 提供复位 Vout 功能，当 RESET# 引脚被拉低时，Vout 会被设置为 VBOOT 值。RTQ8826 提供 VR_Ready 与热指示器。它亦具备完整的故障保护功能，包括过压 (OV)、欠压 (UV)、慢速过电流 (SLOW_OC)、快速过电流 (Fast_OC)、过温 (OT) 与欠压锁定 (UVLO)。RTQ8826 支持多项可通过 I2C/PMBus 接口设置的功能。
