Descripción general

Description

The LM25141RGER is a Texas Instruments synchronous DC-DC buck regulator controller. It drives external MOSFETs to convert a higher input voltage to a regulated lower output with high efficiency. Key capabilities typically include switching-frequency control (fixed or adjustable), voltage- or current-mode regulation, enable/soft-start, and multiple protective features (overcurrent/overvoltage/thermal protection) with fault reporting. It supports multi‑phase operation for high-current VRMs and is suitable for power rails in CPUs, GPUs, telecom, automotive, and industrial applications. The RGER suffix denotes the TI package/version (RoHS, tape-and-reel). For exact electrical specs, pinout, and application circuits, consult the LM25141RGER datasheet and TI design guides.

Package

LM25141RGER is a RoHS-compliant 16-pin VSSOP package with exposed pad (EP).

Pinout

- Pin count: 28 pins (HTSSOP/TSSOP-28 package)
- Function: Dual multiphase PWM controller for synchronous buck regulators (drives/multiphase buck VRMs).

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Company type: A global American semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits (ICs) used in a wide range of electronics.

Application

LM25141RGER is a high-efficiency, multi‑phase, synchronous buck regulator controller. Typical application areas:
- Point‑of‑load power for CPUs/GPUs (high‑current VRMs)
- Server, data‑center, and networking power supplies
- Industrial automation and telecom DC‑DC converters
- Automotive 12V to low rails power management
It enables compact, fast‑transient, high‑current DC‑DC converters for harsh environments.
