Texas Instruments LM5574 Evaluation Board

Texas Instruments LM5574 Evaluation Board is designed to provide a fully functional power converter based on Emulated Current Mode Control to evaluate the TI LM5574 regulator IC. The LM5574 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, which allows for a balance of conversion efficiency and solution size. TI LM5574 regulator IC is an automotive grade step-down switching regulator that delivers 0.5A of continuous output current with an integrated 750mΩ N-channel MOSFET.
