The LM25576MH/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 LM25576 delivers 3A of continuous output current with an integrated 170mR 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 from the regulator to self-synchronize or to synchronize to an external clock. The regulator ensures robustness with cycle-by-cycle current limit, short-circuit protection, thermal shut-down and remote shut-down.
