Overview
The RT9394GQW is a high-performance LED lighting driver IC manufactured by Richtek, designed for applications requiring regulated charge pump technology. It features a tiny WDFN-6 package to minimize board space. The component operates with humidity sensitivity and is supplied in reel or cut tape formats. Factory packaging quantity is 2500 units. The part is identified as an end-of-life product scheduled for obsolescence.
Feature Summary
- Integrates a regulated charge pump architecture for efficient LED driving
- Utilizes a compact WDFN-6 package for small form factor designs
- Designed specifically for LED lighting applications
Applications
- LED lighting systems
- Compact illumination modules
- Space-constrained lighting fixtures
Procurement Notes
Verify current availability status carefully as the manufacturer has declared this component obsolete. Confirm if existing stock remains with authorized distributors or if alternative sourcing channels are required. Check datasheet revisions for any final design-in recommendations before committing to production volumes.
Selection Notes
Consider the WDFN-6 package constraints when designing PCB layouts. Ensure thermal management strategies align with the component's operating conditions. Evaluate system requirements against the regulated charge pump capabilities to confirm suitability for specific LED string configurations.
Part Context
This device belongs to Richtek's LED Lighting Drivers category under Driver ICs. It is distinct from operational amplifiers like the RT9133AGQW or power management solutions for AI servers. The part serves niche lighting applications rather than general-purpose signal processing or high-power server infrastructure.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Due to the end-of-life status, engineers must identify functional equivalents through independent cross-reference tools or contact the manufacturer directly for lifecycle support.
