Checking for live stock

The Texas Instruments LM2574N-12/NOPB is a high-efficiency 12V fixed-output switching voltage regulator (buck converter) ideal for technical and B2B applications in the UK. Supplied in a through‑hole PDIP‑8 (8‑DIP) package, it delivers reliable and stable 12 V at up to 500 mA, making it perfect for power‑supply circuits in demanding environments. Furthermore, compared with generic buck converters, TI's offering ensures long-term availability, strong documentation (including WEBENCH design support), and professional-grade protection, making it a clear choice for discerning technical buyers.

Crucial Features and Benefits of the Product

High Efficiency & Low Heat: Being an SMPS, the LM2574N‑12/NOPB significantly outperforms linear regulators in efficiency, reducing power dissipation to copper traces on the PCB under most conditions.
Minimal External Component Count: Requires only four external components (inductor, diode, input/output capacitors), simplifying design and reducing BOM.
Integrated Protection Features: Includes internal frequency compensation, thermal shutdown, and cycle‑by‑cycle current limiting to safeguard against faults.
Convenient On/Off Control: The TTL-compatible shutdown input enables easy integration into power management schemes for standby or remote control.

Usage Recommendations

Ideal for high-efficiency, compact power supplies in industrial, robotics, and embedded systems where heat dissipation and space are critical. The LM2574N-12/NOPB enables tight voltage regulation and robust performance in harsh UK operating conditions, such as supply voltages up to 40 V or wide temperature ranges. Its through-hole PDIP form makes prototyping and retrofitting straightforward.
