LM25141RGER

LM25141RGER is a Texas Instruments DC-DC buck regulator controller designed for multiphase VRM designs. It drives external high- and low-side MOSFETs and uses current‑mode control for fast, accurate regulation of high-current rails. Key features typically include programmable switching frequency, soft-start, enable and power-good signals, overcurrent/overtemperature protection, undervoltage lockout, and protection for short-circuit conditions. It supports multi‑phase operation to spread load across phases and improve efficiency in CPU/GPU, server, and telecom power rails. The RGER suffix indicates RoHS-compliant, tape-and-reel packaging. For exact electrical specs and recommended application circuits, consult the TI datasheet and WEBENCH.

There isn’t a single exact drop‑in equivalent for LM25141RGER. To cross-reference, please share the device function (DC-DC controller, LED driver, etc.) and key specs: input voltage range, output/current, switching frequency, and package. With that, I can suggest precise cross-references or closest substitutes from TI or other vendors.
