Product Overview

The LM5576MH/NOPB 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 to 75V, the LM5576 delivers 3A of continuous output current with an integrated 170mΩ 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 50 to 500kHz to allow optimization of size and efficiency. To reduce EMI, a frequency synchronization pin allows multiple ICs from the LM(2)557x family to self-synchronize or to synchronize to an external clock. The LM5576 ensures robustness with cycle-by-cycle current limit, short-circuit protection, thermal shut-down and remote shut-down.
