The LM2575HVT-12 from Texas Instruments is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It is capable of driving a 1A load with excellent line and load regulation, offering a fixed 12V output voltage.
This regulator operates with a wide input voltage range and requires only a few external components, simplifying circuit design. It features an internal oscillator with a fixed frequency of 52kHz, internal frequency compensation, and TTL shutdown capability for low power standby mode. The device includes built-in thermal shutdown and current limit protection, enhancing reliability.
Designed as a high-efficiency replacement for linear regulators, the LM2575HVT-12 can significantly reduce the need for large heat sinks. It is housed in a TO-220-5 package suitable for through-hole mounting.
Key electrical characteristics include a 1A output current, 12V fixed output voltage, and an operating temperature range of -40°C to 125°C. The topology is a buck converter with no synchronous rectifier.
