Product Summary

The LM5575MH/NOPB is a 75V, 1.5A Step-Down Switching Regulator. It 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 - 75V, the LM5575MH/NOPB delivers 1.5A of continuous output current with an integrated 330mΩ N-Channel MOSFET. The operating frequency is adjustable from 50kHz to 500kHz to allow optimization of size and efficiency. The LM5575MH/NOPB is supported by the full suite of WEBENCH On-Line design tools.
