General Description

The LM25575 is an easy to use 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 V to 42 V, the LM25575 delivers 1.5-A of continuous output current with an integrated 330-mΩ 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 low-duty cycles associated with current mode regulators.
