The LM5575-Q1 is an easy-to-use buck regulator that 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 V to 75 V, the LM5575-Q1 delivers 1.5 A of continuous output current with an integrated 330-mΩ 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 kHz to 500 kHz to allow optimization of size and efficiency. The LM5575-Q1 ensures robustness with cycle-by-cycle current limit, short-circuit protection, thermal shutdown, and remote shutdown. The device is available in a power enhanced 16-pin HTSSOP package featuring an exposed die attach pad for thermal dissipation. The LM5575-Q1 is supported by the full suite of WEBENCH® on-Line design tools. For AEC-Q100 grade 1 and grade 0 orderable numbers, see the orderable addendum at the end of this data sheet.
