RT6318CGQUF

Overview

The RT6318CGQUF is an 8A synchronous step-down converter with integrated 3.3V and 5V LDOs, manufactured by Richtek USA Inc. It operates from a 5.1V to 23V input range, delivering up to 8A output current at a fixed 750kHz switching frequency. The device features a UQFN-HL-12 package, supports SMD/SMT installation, and functions within a -40°C to +125°C temperature range. With 100µA quiescent current and single output configuration, it serves as a compact power management solution.

Feature Summary

Integrates an 8A synchronous buck converter alongside dedicated 3.3V and 5V low-dropout regulators for multi-rail supply needs.
Utilizes advanced constant on-time control architecture to ensure rapid transient response and stability with all MLCC output capacitors.

Applications

Portable electronic devices requiring efficient multi-voltage generation
Industrial equipment power distribution systems
Embedded computing modules needing compact PMIC solutions

Procurement Notes

Verify the specific suffix CGQUF against official datasheets to confirm pinout and thermal pad configurations. Ensure compatibility with UQFN-HL-12 footprint requirements during PCB layout. Confirm moisture sensitivity level handling procedures are followed according to manufacturer guidelines for surface-mount assembly processes.

Selection Notes

Choose this component when an 8A buck converter combined with fixed LDO outputs is required within a 23V maximum input limit. The fixed 750kHz frequency optimizes passive component size while maintaining efficiency. Consider the UQFN-HL-12 package constraints for thermal dissipation in high-current applications compared to larger packages.

Part Context

This part belongs to Richtek's series of synchronous step-down converters featuring integrated LDOs. It complements similar models like the RT6258CGQUF, which shares comparable electrical characteristics but may differ in factory packaging quantities or specific internal optimizations for different application niches within the broader power management portfolio.

Replacement Considerations

RT6258CGQUF is listed as an alternative option with identical 8A/23V specifications and UQFN-HL-12 packaging. Verify functional equivalence regarding control topology and thermal performance before substitution.
