## Description

The Texas Instruments LM2576HVT-ADJ 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 features a wide input voltage range, supporting up to 60V for the HV version, and an adjustable output voltage range from 1.23V to 57V.

Requiring only four external components, the LM2576HVT-ADJ is simple to use and includes fault protection and a fixed-frequency oscillator operating at 52kHz. It offers a high-efficiency replacement for linear regulators, substantially reducing the need for large heat sinks.

The device is housed in a TO-220 package, making it suitable for through-hole mounting. The operating temperature range is -40°C to 125°C. This regulator is ideal for applications requiring efficient voltage conversion from higher input voltages to lower output voltages.

Key electrical characteristics include a 3A output current capability and a 52kHz internal oscillator. The adjustable output voltage feature provides flexibility for various design requirements. The device also includes TTL-shutdown capability for low-power standby modes.
