Summary
The LM5574 evaluation board is designed to provide the design
engineer with a fully functional power converter based on Emulated Current Mode Control to evaluate the LM5574 regulator IC. The evaluation board provides a 5V output with a 0.5A 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.
