The LM2576HVT-ADJ/LF03 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 device requires a minimal number of external components, making it simple to use and incorporating fault protection.
Key electrical specifications include a wide input voltage range from 4V up to 60V for the HV version, and a specified output current of 3A. The adjustable output voltage can be set between 1.23V and 37V (or up to 57V for the HV version), with a maximum tolerance of ±4% over line and load conditions. It features a fixed switching frequency of 52kHz and offers TTL-shutdown capability for a low-power standby mode.
This regulator is designed as a high-efficiency replacement for popular three-terminal linear regulators, significantly reducing the need for large heat sinks. The component is housed in a TO-220-5 package suitable for through-hole mounting. The LM2576 series offers a robust solution for power management needs where efficiency and simplicity are critical.
