RT8168BGQW

Overview

The RT8168BGQW is a dual-output switching controller designed for Intel IMVP-7 mobile CPU power supplies. It operates with an input voltage range of 5V to 25V and provides two regulated outputs. The device utilizes a WQFN-40 (5x5 mm) surface-mount package suitable for space-constrained designs. It supports PWM control architecture optimized for high-efficiency voltage regulation in portable computing applications.

Feature Summary

• Compliant with Intel IMVP-7 specifications for mobile processor power delivery
• Integrates dual-channel PWM control for core and auxiliary voltage rails
• Supports wide input voltage range from 5V to 25V for flexible system design

Applications

• Intel IMVP-7 compliant mobile CPU power supply modules
• Portable computer motherboard voltage regulation
• Battery-powered device power management systems

Procurement Notes

Verify the specific suffix 'GQW' against the manufacturer's current datasheet to confirm pinout and thermal pad configuration. Confirm RoHS compliance status as indicated in official documentation. Ensure compatibility with existing PCB footprint dimensions for the 40-WQFN package before finalizing procurement orders.

Selection Notes

Select this component when designing for Intel IMVP-7 architecture requirements. Ensure the application requires dual independent output channels. Verify that the 5V-25V input range aligns with the system's power source capabilities. Consider the WQFN-40 package constraints for thermal dissipation and assembly processes.

Part Context

This part belongs to Richtek's specialized PMIC line targeting mobile computing platforms. It serves as a dedicated controller for complex multi-phase VRMs. The device replaces older single-output controllers by integrating dual-channel management within a compact form factor, supporting modern low-voltage, high-current CPU demands.

Replacement Considerations

Check for updated revisions or alternative packages within the same IMVP-7 compatible family. Verify pin-to-pin compatibility if substituting with other dual-output controllers. Confirm that any replacement maintains support for the required Intel VID interface protocols.
