LM5575Q0MH/NOPB Datasheet PDF - TI

●The LM5575-Q1 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 - 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. To reduce EMI, a frequency synchronization pin allows multiple IC’s from the LM(2)557x devices to self-synchronize or to synchronize to an external clock. 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 TSSOP-16 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.
