The LM2575D2T-5R4G from On Semiconductor is a monolithic integrated circuit designed for easy and convenient design of step-down switching regulators (buck converters). This device is capable of driving a 1.0 A load with excellent line and load regulation, featuring a fixed 5.0 V output voltage.
Key electrical specifications include a wide input voltage range from 4.75 V to 40 V and a fixed switching frequency of 52 kHz. The regulator offers high efficiency, significantly higher than linear regulators, especially with higher input voltages. It includes features such as cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions.
Designed to minimize external components, the LM2575 series typically requires only four external components for a complete power supply design. This specific part, the LM2575D2T-5R4G, comes in a surface mount D2PAK-5 package, suitable for applications where space and thermal performance are critical. The operating temperature range is -40°C to 125°C (TJ).
This regulator is ideal for simple and high-efficiency step-down power supplies. Its robust design and integrated protection features make it a reliable choice for various applications.
