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-mΩ 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. To reduce EMI, a frequency synchronization pin allows multiple ICs from the LM(2)557xdevices to self-synchronize or to synchronize to an external clock. The LM5575-Q1 ensuresrobustness with cycle-by-cycle current limit, short-circuit protection, thermal shutdown, andremote shutdown. The device is available in a power enhanced 16-pin HTSSOP package featuring anexposed die attach pad for thermal dissipation. The LM5575-Q1 is supported by the full suite ofWEBENCH® On-Line design tools.
