RT6256CHGQUF

Overview

The RT6256CHGQUF is a mixed-signal PMIC from Richtek USA Inc., integrating one synchronous buck converter and one low-dropout linear regulator (LDO). The buck output delivers up to 6A with adjustable or fixed voltage options, while the LDO provides a fixed 5V at 100mA. Operating within a 5.1V to 23V input range, it features a 750kHz switching frequency. Packaged in a 12-UQFN-HL (3x3mm) footprint, it supports surface mount installation and functions across a -40°C to 125°C junction temperature range.

Feature Summary

• Integrates a high-current synchronous buck converter with an auxiliary LDO for combined power management needs.
• Supports flexible output configurations via adjustable or fixed voltage settings on the primary channel.
• Operates reliably across extended industrial temperature ranges with robust thermal performance.

Applications

• Portable electronic devices requiring compact dual-rail power solutions
• Industrial control systems needing stable voltage regulation under varying loads
• Embedded systems utilizing mixed-signal power architectures

Procurement Notes

Verify the specific suffix 'CHGQUF' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering quantity matches the standard packaging configuration of 3,000 units per reel. Confirm RoHS compliance status if required by your assembly process standards.

Selection Notes

Select this component when a single IC solution is preferred for managing both high-current digital logic and lower-current analog peripherals. The integrated topology reduces board space compared to discrete designs. Ensure the application input voltage remains within the 5.1V to 23V operational window for optimal efficiency and stability.

Part Context

This device belongs to the RT6256 family of mixed-signal power management ICs. It combines switching and linear regulation technologies to provide versatile power distribution in minimal footprint applications. The UQFN package facilitates high-density PCB layouts common in modern portable and industrial electronics.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains identical pinout, thermal characteristics, and electrical ratings to avoid redesigning the power stage or layout.
