DescriptionThe LM25576-Q1 is an easy to use buck regulator which allows design engineers to designand optimize a robust power supply using a minimum set of components. Operating with an inputvoltage range of 6 V to 42 V, the LM25576-Q1 delivers 3 A of continuous output current with anintegrated 170-m? N-Channel MOSFET. The regulator utilizes an Emulated Current Mode architecturewhich provides inherent line regulation, tight load transient response, and ease of loopcompensation without the usual limitation of low-duty cycles associated with current moderegulators. The operating frequency is adjustable from 50 kHz to 1 MHz to allow optimization ofsize and efficiency. To reduce EMI, a frequency synchronization pin allows multiple IC’s from theLM(2)557x family to self-synchronize or to synchronize to an external clock. The LM25576-Q1 ensuresrobustness with cycle-by-cycle current limit, short-circuit protection, thermal shut-down, andremote shut-down. The device is available in a power enhanced HTSSOP-20 package featuring anexposed die attach pad for thermal dissipation. The LM25576-Q1 is supported by the full suite ofWEBENCH? On-Line design tools.
