Description
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.
