The RT8809A RT8809AGQW 07= Marking 07 IC PWM Controller IC is a high-performance 3-phase synchronous buck controller designed for Intel and AMD CPU core voltage regulation. It provides precise multi-phase control, fast transient response, and high conversion efficiency for advanced power management systems.
This IC integrates a 3-phase PWM controller with current balancing, Power Good indication, and Dynamic Voltage Identification (VID) support, ensuring reliable and flexible CPU voltage control. It also includes complete protection features such as Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), Over-Current Protection (OCP), and Under-Voltage Lockout (UVLO).
Packaged in a compact QFN form factor, the RT8809AGQW is identified by marking code “07=” and is ideal for use in motherboards, VRMs, and embedded computing systems requiring multi-phase CPU power regulation.
