RT8884BGQW

Overview

The RT8884BGQW is a multi-phase PWM controller designed for CPU core power supplies, manufactured by Richtek USA Inc. It operates with a buck topology and provides four output channels. The device accepts an input voltage range of 4.5V to 5.5V and delivers adjustable output voltages from 500mV to 3.6V. It functions within a temperature range of -40°C to +85°C and utilizes a 32-WQFN (4x4) package.

Feature Summary

Multi-phase PWM control architecture optimized for CPU core power supply applications
Integrated buck switching controller supporting four independent output channels
Compatible with Intel VID interface standards for dynamic voltage scaling

Applications

CPU core power supply regulation
Intel platform voltage control
Server and workstation mainboard power distribution

Procurement Notes

Verify the specific suffix 'GQW' against the manufacturer's current datasheet to confirm pinout and thermal pad configuration. Ensure compatibility with the target PCB footprint, specifically the 32-WQFN (4x4) dimensions. Confirm that the design supports the required input voltage range of 4.5V to 5.5V before finalizing procurement.

Selection Notes

Select this component when designing power stages for processors requiring multi-phase control and Intel VID compatibility. It is suitable for applications needing precise voltage regulation between 500mV and 3.6V. Consider the 32-WQFN package size for space-constrained designs operating within the specified industrial temperature range.

Part Context

This part belongs to the RT8884 series of multi-phase controllers from Richtek. It is categorized under PMICs and Switching Controllers. The device is distinct from single or dual-phase variants like the RT8238 or RT8810, offering higher channel density for complex processor power delivery systems.

Replacement Considerations

The RT8884BN-A is listed as an alias for this part number. Verify if other suffixes in the RT8884 family offer identical electrical characteristics and pinouts before substitution.
