Offline switcher for LED lighting — topology-flexible, SOT-23-5
The TPS92411DBVR is an AC DC offline switcher from Texas Instruments, purpose-built for lighting applications. It integrates the switch internally and supports flyback, step-down (buck), and step-up (boost) topologies, giving the board designer one device that can serve constant-current LED drivers across multiple power-stage architectures.
Package and board-fit — SOT-23-5
Surface-mount assembly only; the small outline keeps the layout simple for a single-layer or two-layer board.
Texas Instruments lists this part as Active in production, with ROHS3 compliance.
