LM25575MH/NOPB

The LM25575MH/NOPB is a SIMPLE SWITCHER® Step-down Switching 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 to 42V, the LM25575 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 low-duty cycles associated with current mode regulators. The operating frequency is adjustable from 50kHz to 1MHz to allow optimization of size and efficiency. To reduce EMI, a frequency synchronization pin allows multiple IC's of this regulator to self-synchronize or to synchronize to an external clock.
