The LM2575T-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 line 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 requiring only four external components. It also incorporates thermal shutdown and current limit protection to safeguard against fault conditions. The LM2575T-ADJ is available in a TO-220 package and is optimized for use with standard inductors, enhancing its efficiency and ease of integration into power supply designs. Engineers looking for a reliable and efficient solution for step-down voltage regulation may consider the LM2575T-ADJ for their projects.
