Hello,

Could you review attached LMZ31710 schematic and let me get the result?

LMZ31710.pdf

Under attached schematic, 5.5V out is coming without any load, but connect some load, output voltage drop to 2.1V.

Please let me get your review result ASAP.

Regards,

Nicky

    Do you have the PH pins connected to one another? The schematic shows the PH not connected.
    Can you send a waveform of the 5.5V rail, with and without load applied?
    Please contact be offline at jarrigo@ti.com with other questions.
    Thanks, Jason
