The LM2575-N is a monolithic integrated circuit designed as a step-down (buck) switching regulator, capable of delivering up to 1A of output current. It features a wide input voltage range from 40V to 60V for the high-voltage version, with an adjustable output voltage range from 1.23V to 37V, maintaining a regulation tolerance of ¬±4%. The device operates at a fixed frequency of 52 kHz, which simplifies the design process by requiring only four external components. This regulator includes built-in thermal shutdown and current limit protection, ensuring reliable operation under fault conditions. It is optimized for high efficiency, making it a suitable replacement for traditional linear regulators, thereby reducing the need for large heat sinks. The LM2575-N is available in various package types, including TO-220 and surface-mount options, facilitating integration into different designs. Its low standby current of 50 OºA (typical) and TTL shutdown capability further enhance its usability in power-sensitive applications.
