RT8106GQW

Overview

The RT8106GQW is a synchronous buck DC-DC switching controller manufactured by Richtek USA Inc. It operates with an input voltage range of 4.75V to 13.2V and features a fixed switching frequency of 300kHz. The device provides a single positive output configuration housed in a 10-WDFN (3x3) package with an exposed pad. It supports surface mount installation and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Synchronous rectification architecture for improved efficiency
• Integrated enable and power good control signals
• Single-phase step-down topology design

Applications

• Point-of-load regulation for embedded systems
• General purpose DC-DC conversion modules
• Industrial control power supplies

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix GQW matches the required 10-WDFN package variant. Check RoHS compliance documentation against current regulatory standards. Validate that the part status reflects end-of-life notifications if sourcing from secondary markets.

Selection Notes

Select this controller when external MOSFETs are preferred over integrated switches. Ensure the application requires a 300kHz switching frequency compatible with standard passive components. Verify that the 4.75V minimum input voltage aligns with the system supply rails. Confirm thermal management strategies suit the 10-WDFN package constraints.

Part Context

This component belongs to the Richtek RT8106 family of synchronous buck controllers. It is designed for applications requiring high efficiency and compact footprint solutions. The device integrates gate drivers for external N-channel MOSFETs, distinguishing it from fully integrated regulator ICs.
