Overview
The RT5041ABGQW is a special purpose regulator controller designed for DDR memory applications. It integrates five fixed output voltage rails: 1.05V, 1.15V, 1.24V, 1.5V, and 1.82V. The device operates with an input voltage range of 2.7V to 5.5V. It is housed in a 28-WQFN package with an exposed pad. This component is classified as obsolete and is no longer manufactured by Richtek USA Inc.
Feature Summary
- Integrated multi-rail voltage generation for DDR systems
- Fixed output voltage configuration eliminating external resistor networks
- Controller architecture for power management integration
Applications
- DDR memory controller power supplies
- System-on-chip (SoC) peripheral voltage regulation
- Embedded computing platforms requiring stable memory voltages
Procurement Notes
Verify component authenticity carefully as the RT5041ABGQW is officially obsolete. Confirm manufacturing date codes and packaging integrity upon receipt. Ensure compatibility with existing PCB layouts due to the specific 28-WQFN footprint. Check for valid RoHS compliance documentation if required for current production standards.
Selection Notes
Select this part only for legacy designs utilizing DDR interfaces requiring these specific voltage levels. Evaluate alternative modern PMICs for new developments due to obsolescence. Ensure input voltage constraints between 2.7V and 5.5V align with system power rails. Verify thermal performance requirements for the WQFN package in the target enclosure.
Part Context
Richtek Technology Corporation specializes in analog ICs and power management solutions. The RT5041ABGQW belongs to their special purpose regulator portfolio, targeting memory subsystems. As an obsolete component, it represents earlier generations of DDR power control technology previously used in embedded and industrial electronics.
Replacement Considerations
No public confirmed substitute part numbers are available for the RT5041ABGQW. Designers must consult Richtek for current equivalents or redesign using modern multi-output regulators compatible with the target DDR specifications.
