LM2576T-12 Buck 12V 3A 40V TO-220-5 DC-DC Converters DIP IC
The LM2576T-12 is a monolithic integrated circuit designed as a step-down (buck) switching regulator, delivering a fixed 12V output at up to 3A. This makes it an ideal solution for powering microcontrollers, sensors, and other digital circuits that require a stable voltage supply. Its high efficiency and minimal external component requirements make it a preferred choice for both hobbyists and professional engineers in the electronics industry, particularly for those developing products for e-commerce platforms.
Features:
- Fixed 12V output voltage with 3A maximum output current.
- Wide input voltage range from 4V to 40V.
- High efficiency (up to 80%) for minimal heat generation.
- Integrated thermal shutdown and overcurrent protection.
- Low output ripple for stable power delivery.
- TO-220-5 package for through-hole mounting.
