The LM5574 is an easy-to-use SIMPLE SWITCHER ® buck regulator that allows design engineers to design and optimize a robust power supply with a minimal set of components. With 6 input voltage ranges - 75V, the LM5574 provides a continuous output with an integrated 750mΩn channel MOSFET current of 0.5A. The regulator uses an analog current-mode architecture that provides no inherent line gauge inherent in the low duty cycle general limitations associated with current-mode regulators, accurate load transient response, and loop compensation mitigation. The operating frequency is adjustable from 50kHz to 500kHz for optimized size and efficiency. To reduce electromagnetic interference, the frequency sync pin allows self-synchronization from multiple ICs of the LM(2)557x family to an external clock. Robust LM5574 with cycle-by-cycle current limit, short-circuit protection, thermal shutdown, and remote shutdown are guaranteed. The device is available in a TSSOP - 16 package. The LM5574 is a complete suite of supported WEBENCH online design tools.
