RT8167BGQW

Overview

The RT8167BGQW is a dual single-phase PWM controller compliant with Intel IMVP-7 specifications, designed for CPU core and GPU core power supplies. It operates within an input voltage range of 5V to 25V and provides two adjustable output channels ranging from 500mV to 3.6V. The device supports switching frequencies up to 1MHz per phase and features integrated MOSFET drivers. It utilizes a Serial VID interface for voltage programming via an 8-bit DAC with 5mV steps. The component is housed in a compact 48-WQFN (6x6mm) package and operates reliably across temperatures from -40°C to +85°C.

• Includes built-in high-accuracy DAC for precise VID code conversion
• Features differential remote voltage sensing for improved load regulation

Applications

• Intel IMVP-7 compatible CPU core power supply designs
• GPU core power supply architectures
• Laptop computer mainboard power systems
• AVP step-down converter implementations

Procurement Notes

Verify the specific suffix 'GQW' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the revision level to confirm support for all intended Intel AVP states. Confirm moisture sensitivity levels prior to surface mount assembly processes.

Selection Notes

Select this controller when designing power stages requiring strict adherence to Intel IMVP-7 standards for both CPU and GPU rails. The integrated driver capability reduces external component count compared to discrete solutions. Consider the 48-WQFN package size constraints during layout planning. Verify that the system requires SVID communication for dynamic voltage scaling rather than fixed resistor programming.
