The LM5574 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 6V to 75V, the LM5574 delivers 0.5A of continuous output current with an integrated 750mΩ N-Channel MOSFET. The regulator uses 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 50kHz to 500kHz to allow optimization of size and efficiency. To reduce EMI, a frequency synchronization pin allows multiple ICs from the LM(2)557x family to self-synchronize or to synchronize to an external clock. The LM5574 makes sure of robustness with cycle-by-cycle current limit, short-circuit protection, thermal shutdown, and remote shutdown. The device is available in a 16-pin TSSOP package. The LM5574 is supported by the full suite of WEBENCH online design tools.
