TPSM82901SISR

TPSM82901SISR is TI’s TPSM family high‑efficiency buck regulator in a compact power‑module package. It provides a regulated low‑voltage supply from a higher input for point‑of‑load applications in embedded, automotive, and industrial systems. It is a fully integrated DC‑DC converter that minimizes external parts, delivering high efficiency, good load and line regulation, and fast transient response. The device includes protection features such as enable control, UVLO, overcurrent protection, thermal shutdown, and overvoltage protection. Typical applications include microprocessors, FPGAs, memory, ASICs, sensors, and other on‑board rails. Package: SISR variant denotes TI’s small, surface‑mount power module with a compact footprint and straightforward PCB integration. Design notes: select the desired output voltage, connect enable appropriately, and follow TI’s reference designs for input/output capacitors, layout, and any compensation requirements. For exact electrical specs, pinout, mechanical drawings, and evaluation boards, consult the TPSM82901SISR product page and the datasheet.

The TPSM82901SISR is manufactured by Texas Instruments (TI). TI is an American semiconductor company that designs and manufactures integrated circuits and semiconductor devices—especially analog ICs, power-management products, and embedded processors—serving industrial, automotive, consumer, and communications markets. It is a large, publicly traded technology company (NASDAQ: TXN) headquartered in Dallas, Texas.

TPSM82901SISR is a 1-A step-down regulator in a compact power-module package. Typical applications:
- Point-of-load buck regulator for FPGAs, CPUs/MCUs, DSPs and memory (DDR/SRAM)
- Core and auxiliary rails in embedded/mobile devices (smartphones, tablets, wearables)
- Networking/telecom gear and data-center boards needing compact, efficient power
- Automotive and industrial control systems requiring robust, small-footprint regulation
- Distributed power architectures and ASIC/SoC power rails
- Space-constrained instruments and portable equipment needing fast transient response and high efficiency
