Description

DC-DC CONV BUCK 500KHZ HTSSOP-16
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-ofloop compensation without the usual limitation of lowduty 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.
