The LM2576HVT-ADJ/NOPB from Texas Instruments is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving a 3A load with excellent line and load regulation. This regulator requires a minimum number of external components, making it simple to use and incorporating fault protection and a fixed-frequency oscillator.
Key electrical specifications include a wide input voltage range of up to 60V for the HV version, and an adjustable output voltage range from 1.23V to 37V (or 57V for HV version) with ±4% maximum line and load regulation. It operates at a fixed frequency of 52kHz and can deliver up to 3A of output current. The device also includes TTL-shutdown capability for a low-power standby mode.
This regulator is housed in a TO-220 package, suitable for through-hole mounting. The operating temperature range is -40°C to 125°C. The LM2576 series offers a high-efficiency replacement for popular three-terminal linear regulators, significantly reducing the size of the required heat sink.
