LM2575HVT-ADJ Description

Short technical summary and product information.

The LM2575HVT-ADJ from Texas Instruments is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving a 1A load with excellent line and load regulation. This adjustable version allows for a wide output voltage range from 1.23V up to 37V, with a maximum tolerance of ±4% over line and load conditions.

 

The device features a wide input voltage range, supporting up to 60V for the HV version. It operates at a fixed frequency of 52kHz, simplifying design by requiring only four external components and including internal frequency compensation. The regulator offers high efficiency, making it a suitable replacement for linear regulators, often eliminating the need for a heat sink.

 

Key features include thermal shutdown and current limit protection, ensuring robust operation. The LM2575HVT-ADJ is supplied in a TO-220-5 package suitable for through-hole mounting. Its design is optimized for use with readily available standard inductors, further simplifying the development of switch-mode power supplies.
