LMZ31704: LMZ31704 can't work

Part Number: LMZ31704

Hi, LMZ31704 is designed to output dc5V at 3A from dc6V~12v. And we found that output voltage is not 5V, below it.The ouput voltage will change with input. With load improved, the output voltage descrease. could you please give some help about it. Than  ks!

  • How are you powering this board? Is the current limit of the input power supply increased to deliver the required power? Can you send waveforms of both VIN and VOUT? Can you send waveform with VIN = 6V and VIN=12V?
    You can contact me directly at jarrigo@ti.com to send waveforms.
