Categories: DC DC Switching Regulators
Quality Control: Learn More
The Microchip Technology LM2576BU is a versatile 3A step-down switching regulator designed for efficient voltage conversion. This component features an adjustable output voltage, with a minimum fixed output of 1.23V, capable of reaching up to 37V. Operating with an input voltage range from 4V to 40V, the LM2576BU utilizes a buck topology and switches at a nominal frequency of 52kHz. It provides a single positive output and does not incorporate a synchronous rectifier, simplifying external component selection. The device is housed in a TO-263-5 package, suitable for surface mounting applications. This regulator finds utility in various industrial sectors including telecommunications, medical equipment, and consumer electronics, where reliable power management is critical.
