The LM2594HVN-12/NOPB from Texas Instruments is a simple and reliable step-down (Buck) switching regulator with a fixed 12V output. It features a wide input voltage range from 4.5V to 60V, making it ideal for high-voltage industrial and automotive applications. Capable of delivering 500mA of output current, it operates at a 150kHz switching frequency. The 8-DIP package is easy to use and solder, making it suitable for through-hole PCB designs. This converter offers a robust and cost-effective solution for generating a regulated 12V rail.
- High 60V Input Voltage: Safely handles 48V industrial rails and automotive transients without external protection.
- Simple Fixed 12V Output: Requires minimal external components, simplifying design and BOM.
- Proven, Rugged Design: Based on the popular LM259x family, known for reliability and ease of use.
- 150kHz Switching Frequency: Well-suited for noise-sensitive applications and compatible with standard components.
- Through-Hole 8-DIP Package: Easy to prototype and assemble, ideal for industrial control boards.
