www.DataSheet4U.com LM5575 75V, 1.5A Step-Down Switching Regulator January 2007 LM5575 75V, 1.5A Step-Down Switching Regulator General Description The LM5575 is an easy to use SIMPLE SWITCHER® buck regulator which allows design engineers to design and optimize a robust power supply using a minimum set of components. Operating with an input voltage range of 6 - 75V, the LM5575 delivers 1.5A of continuous output current with an integrated 330mΩ N-Channel MOSFET. The regulator utilizes an Emulated Current Mode architecture which provides inherent line regulation, tight load transient response, and ease of loop compensation without the usual limitation of lowduty cycles associated with current mode regulators.
