RT8167AGQW

Overview

The RT8167AGQW is a dual single-phase PWM controller designed for CPU core and graphics power supplies, compliant with Intel IMVP-7 and VR12 specifications. It operates within an input voltage range of 5V to 25V and provides two independent outputs adjustable from 500mV to 3.6V. The device supports a switching frequency of 1MHz and delivers up to 40mA output current. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in a 48-WQFN (6x6mm) package.

Feature Summary

• Dual-channel architecture supporting simultaneous control for CPU core and graphics power domains
• Compliance with Intel IMVP-7 and VR12 regulator standards for modern processor power delivery
• Integrated buck topology enabling efficient step-down conversion from standard bus voltages

Applications

• CPU core power supply design
• Graphics processing unit (GPU) power regulation
• Intel IMVP-7 compatible motherboard architectures
• VR12 standard power management systems

Procurement Notes

Verify the complete part number including suffixes such as AGQW to ensure correct packaging and tape-and-reel configuration. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling. Cross-reference manufacturer datasheets for specific ordering information and lead times associated with the 48-WQFN package variant.

Selection Notes

Select this component when designing power stages requiring strict adherence to Intel IMVP-7 or VR12 protocols. Ensure the application demands dual independent outputs for separate core and GFX rails. Verify that the 1MHz switching frequency aligns with thermal and efficiency targets for the specific PCB layout constraints.

Part Context

This device belongs to the Richtek RT8167 family of specialized power management ICs. It serves as a dedicated controller rather than a complete integrated circuit, requiring external MOSFETs and passive components to form the final power stage. The product line targets high-performance computing platforms where precise voltage regulation is critical.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative controllers based on pin compatibility, protocol support, and electrical specifications only after consulting official manufacturer cross-reference guides.
