The LM2574MX-3.3 is a highly efficient, step-down (buck) switching regulator integrated circuit (IC) component produced by Texas Instruments. It is specifically designed to provide a fixed 3.3V output voltage from a wide input voltage range, making it ideal for various applications in the electronics industry. Here is an overview of its key features:
1. High Efficiency: The LM2574MX-3.3 offers high efficiency with a maximum conversion efficiency of up to 85%. This efficiency minimizes power loss and enhances overall system performance.
2. Wide Input Voltage Range: It can accommodate a broad input voltage range, typically from 7V to 40V. This wide range makes it compatible with numerous power sources, including batteries, automotive systems, and industrial power supplies.
3. Fixed Output Voltage: The IC delivers a precisely regulated 3.3V output voltage, which remains constant even with fluctuations in the input voltage. This stability allows for reliable and consistent operation of downstream electronics.
4. Adjustable Switching Frequency: The switching frequency, ranging from 50kHz to 52kHz, can be externally adjusted based on the specific requirements of the application. This flexibility enables optimization for efficiency or size, depending on the design constraints.
5. Internal Compensation: The LM2574MX-3.3 includes an internal compensation network, simplifying the external component count and layout considerations. It saves board space and minimizes the possibilities of external component selection errors
