LM5575EVAL: 5V @ 1.5A, 7 ~ 75 Vin

Summary

The LM5575 evaluation board is designed to provide the design engineer with a fully functional power converter based on Emulated Current Mode Control to evaluate the LM5575 regulator IC. The evaluation board provides a 5V output with a 1.5A current capability. The ultra-wide input voltage ranges from 7V to 75V. The design operates at 300kHz, a good compromise between conversion efficiency and solution size.
