Texas Instruments LM2575-N SIMPLE SWITCHER 1A Step-Down Voltage Regulator LM2575S-ADJ

The LM2575S-ADJ is a monolithic integrated circuit designed as a step-down (buck) switching regulator, capable of delivering an output current of up to 1A. It features an adjustable output voltage range from 1.23V to 37V, with a regulation tolerance of ¬±4% under specified input and load conditions. The device operates with a wide input voltage range of 40V to 60V for the high-voltage version, making it suitable for various applications. This regulator includes internal frequency compensation and a fixed-frequency oscillator operating at 52 kHz, which simplifies the design process by minimizing the number of external components required,Äîonly four are needed. It also incorporates thermal shutdown and current limit protection to ensure reliable operation under fault conditions. The LM2575S-ADJ is available in a TO-263 package, which is advantageous for applications requiring compact design and efficient thermal management. Engineers may consider this product for applications such as high-efficiency step-down regulation, pre-regulation for linear regulators, and on-card switching regulators, among others.
