The LM2575 series of regulators are monolithic integrated circuits that provide all the active functions for a step - down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V, and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed - frequency oscillator.
The LM2575 series offers a high - efficiency replacement for popular three - terminal linear regulators. It substantially reduces the size of the heat sink, and in many cases no heat sink is required.

Texas Instruments LM2575HVS-ADJ's Category - Power Management（PMIC）
Power management chip is a chip that undertakes the responsibilities of power conversion, distribution, detection and other power management in the electronic equipment system. It is mainly responsible for identifying the power supply amplitude of the CPU, generating corresponding short-duration waves, and promoting the subsequent circuit to perform power output. Power management chip refers to a chip that is responsible for managing power conversion, distribution, detection, etc. in an electronic equipment system. Its performance and reliability directly affect the working efficiency and service life of electronic equipment and is a key device in electronic equipment. More details: Power Management Chip (PMIC).
Manufacturer of LM2575HVS-ADJ - Texas Instruments
TI is an international semiconductor company in the United States, headquartered in Dallas, Texas. The company was established in 1930 and has more than 100 offices worldwide, with more than 43,000 employees in the United States, Europe, Asia, and Latin America. TI is a global leading semiconductor manufacturer and has an important influence on multiple fields such as computers, communications, industrial control, and healthcare.
The history of Texas Instruments can be traced back to 1930 when inventor and engineer James Korklewski established Geophysical Service Incorporation to create a sales company for electronic equipment. In 1941, TI was restructured into an independent company and began to engage in scientific and technological research and development and semiconductor production. TI first introduced transistors in the 1950s. In the 1960s, the company began to engage in the integrated circuit industry and produced the world's first single-chip microcomputer in 1971, which greatly changed the development model of the computer industry.
Texas Instruments products include analog integrated circuits, digital signal processors, single-chip microcontrollers, power management devices, chip solutions, and radio frequency controllers. These electrical components are sold to the aerospace, defense, industrial, personal electronics, and communications markets. They cover portable audio devices, high-definition televisions, car navigation, mobile phones, automotive signal processing, industrial control equipment, and security protection.
Texas Instruments' globalization strategy relies on an understanding of cross-cultural, language, and technology. In the past few decades, TI has expanded its business globally. It is very popular in the Asian market. The company has opened offices and factories in China, Southeast Asia, and India, aiming to expand its market share and improve competitiveness.
