LM5576MHX Product Details

LM5576MHX Description


Construct engineers can easily design and optimize a reliable power supply utilizing the SIMPLE SWITCHER? buck regulator, LM5576, and a small number of components. The LM5576 generates 3 A of continuous output current with an inbuilt 170 m N-Channel MOSFET while operating with an input voltage range of 6 to 75 V. The regulator uses an Emulated Current Mode architecture that offers tight load transient response, inherent line regulation, and ease of loop compensation without the typical restriction of low-duty cycles associated with current mode regulators. The working frequency can be adjusted between 50 kHz and 500 kHz to maximize size and effectiveness.
