概述

Description

TPSM82901SISR is a Texas Instruments single‑channel buck regulator in the TPSM family, designed for compact point‑of‑load power rails. It integrates the high‑ and low‑side FETs and a switch‑mode controller to convert a higher input voltage to a stable, lower output with high efficiency. The device supports fixed or adjustable output via an external resistor network, along with enable control, soft‑start, and built‑in protections (overcurrent, thermal shutdown, undervoltage lockout). The SISR suffix denotes a specific packaging/rail option. It is intended for space‑constrained applications such as CPU cores, GPUs, memories, and embedded controllers where board footprint is critical. For exact electrical specs (VIN range, VOUT, max output current, switching frequency, efficiency, and package details), consult the TPSM82901SISR datasheet and TI product page.

Package

TPSM82901SISR is in a VQFN-8 (3x3 mm) leadless package with an exposed thermal pad (thermally enhanced).

Manufacturer

Manufacturer: Texas Instruments (TI).
Type of company: TI is an American multinational semiconductor company that designs and manufactures analog and mixed‑signal integrated circuits, embedded processors and power‑management devices for industrial, automotive, communications and consumer electronics applications; headquartered in Dallas, Texas.

Application

TPSM82901SISR is a compact, high-efficiency buck regulator used as a power-management solution for space‑constrained boards. Typical applications include portable/mobile devices, wearables and IoT sensors, embedded MCU/SoC rails, data-logging and consumer electronics, as well as automotive and industrial electronics requiring a robust PMIC solution. It also serves as a point‑of‑load regulator for DSPs, FPGAs, memory, and microcontrollers in telecom/network equipment.

Equivalent

There is no single exact, guaranteed drop‑in cross‑reference for TPSM82901SISR. To find equivalents match key specs (VIN range, VOUT, max I, switching freq, package/footprint). Comparable integrated buck-module families to consider: TI TPSM series, MPS MPM series, Murata power modules (UWE/OKI), and Analog Devices/Linear Tech µModule LTM family. Provide the TPSM82901SISR electrical and mechanical specs and I’ll recommend direct replacements.
