The LM2575HVT-5.0 DC-DC Converters is manufactured by HGSEMI and is a TO-220-5 RoHS compliant part. It is a step-down switching regulator specifically designed to supply a low voltage from a higher voltage input. It is based on HGSEMI's Enhanced version of the popular LM2575 integrated circuit, and operates from 4.5V to 40V input range, and a fixed output of 5V. It features a 1.8MHz fixed frequency with a VCC of 8.0V operation, and a 2A peak current limit. The LM2575HVT-5.0 features a thermal shutdown function, and short-circuit and over-temperature protection. It also has a typical efficiency rating of 75%. This product is an ideal solution for applications that require a reliable and efficient DC-DC switching regulator with a wide input range, and a fixed, regulated 5V output.
