LM5575MHX/NOPB | Texas Instruments

Step-Down Switching Regulator, LM5575MHX/NOPB, Texas Instruments

The LM5575MHX/NOPB is an easy-to-use SIMPLE SWITCHER® buck regulator which allows a design engineer 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 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 the LM5575MHX/NOPB to self-synchronize or synchronize to an external clock. The LM5575MHX/NOPB ensures robustness with cycle-by-cycle current limit, short-circuit protection, thermal shutdown, and remote shutdown.
