DescriptionThe LM5575MH/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 - 75V, the LM5575MH/NOPB delivers 1.5A of continuous output current with an integrated 330m? 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 500kHz to allow optimization of size and efficiency. To reduce EMI, a frequency synchronization pin allows multiple IC’s from the LM(2)557x family to self-synchronize or to synchronize to an external clock. The LM5575MH/NOPB ensures robustness with cycle-by-cycle current limit, short-circuit protection, thermal shut-down, and remote shut-down. The device is available in a power enhanced HTSSOP-16 package featuring an exposed die attach pad for thermal dissipation. The LM5575MH/NOPB is supported by the full suite of WEBENCH On-Line design tools.
