3 Description
The LM25576-Q1 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 LM25576-Q1 delivers 3 A of continuous output current with an integrated 170-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. The operatin...
