Power Supply Controllers, Monitors Procurement Notes

This specific part number is listed as obsolete or discontinued by the manufacturer. Verification of availability through authorized distributors is essential, as stock may be limited or non-existent. Alternative sourcing strategies should be considered due to the end-of-life status. Confirming the exact suffix (e.g., G4) is critical when evaluating potential substitutes or remaining inventory.

Power Supply Controllers, Monitors Selection Notes

Designers should evaluate the UC2849 for applications requiring secondary side average current mode control. Given its obsolete status, alternative components with similar control architectures must be identified. Ensure that any replacement supports the required input voltage range and thermal operating conditions while maintaining compatibility with the existing system topology.

Power Supply Controllers, Monitors Part Context

The UC2849 belongs to the Texas Instruments family of low-dropout voltage controllers. It is categorized under Power Management ICs (PMIC). This specific variant utilizes a SOIC-24 package and is designed for specialized control applications distinct from standard switching controllers like the UC2846 series found in related product listings.

Power Supply Controllers, Monitors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the obsolete status, engineers must identify functional equivalents based on control method and electrical specifications rather than direct cross-references.
