The LM5575-Q1 is an easy-to-use buck regulator that allows design engineers to design andoptimize a robust power supply using a minimum set of components. Operating with an input voltagerange of 6 V to 75 V, the LM5575-Q1 delivers 1.5 A of continuous output current with an integrated330-m? N-channel MOSFET. The regulator utilizes an emulated current mode architecture whichprovides inherent line regulation, tight load-transient response, and ease-of-loop compensationwithout the usual limitation of low-duty cycles associated with current mode regulators. Theoperating frequency is adjustable from 50 kHz to 500 kHz to allow optimization of size andefficiency. The LM5575-Q1 ensures robustness with cycle-by-cycle current limit, short-circuitprotection, thermal shutdown, and remote shutdown. The device is available in a power enhanced16-pin HTSSOP package featuring an exposed die attach pad for thermal dissipation. The LM5575-Q1 issupported by the full suite of WEBENCH? on-Linedesign tools. For AEC-Q100 grade 1 and grade 0 orderable numbers, see the orderable addendum at theend of this data sheet.
