RT8816BGQW

Overview

The RT8816BGQW is a dual-phase PWM controller with VID reference, designed for CPU core power supplies. It operates at a switching frequency of 300 kHz and supports an output voltage range of 1.33 V to 2 V. The device features four outputs and utilizes a WQFN-20 package. It functions within a temperature range of -10°C to +105°C and accepts input voltages between 2.5V and 26V.

Feature Summary

• Dual-phase PWM control architecture
• VID reference interface compatibility
• Integrated synchronous buck topology

Applications

• CPU core power supply regulation
• Multi-phase DC-DC conversion systems
• High-performance computing platforms

Procurement Notes

Verify the specific suffix 'BG' against official Richtek documentation to confirm pinout and electrical characteristics. Ensure the WQFN-20 package matches the target PCB footprint. Confirm humidity sensitivity level requirements for assembly processes. Validate that the 300 kHz switching frequency aligns with system thermal constraints.

Selection Notes

Select this component when a dual-phase solution with VID interface is required. Compare against other RT8816 variants for specific voltage ranges or package options. Ensure the operating temperature range meets the application environment. Verify compatibility with the intended memory or processor VID signals.
