Overview
The LM2576HVSX-12/NOPB is a high-performance DC-DC switching regulator produced by Texas Instruments (not National Semiconductor, as National Semiconductor was acquired by Texas Instruments in 2011). The LM2576HVSX-12/NOPB is part of the SIMPLE SWITCHER® family, designed to provide a low component count step-down voltage regulation solution. This regulator is capable of handling input voltages from 4V to 60V and can deliver a fixed output voltage of 12V with a maximum continuous current of 3A. It is ideal for applications requiring high efficiency and minimal external components.
