LM5007: VIN UVLO value

Binbin Wang
Prodigy 150 points
Part Number: LM5007

Hi team,

My customer use LM5007 to supply PSE 3.3V. The input voltage is 48V, output voltage is 3.3V, output current is 0.17A. I search datasheet and can't find UVLO value of VIN, just find that VCC UVLO is 6.3V. I am wondering if the device may work when input voltage is above 10V and below 18.5V. Could you please provide typical value for VIN UVLO, thanks.

BRs,

Binbin Wang

    Hi Binbin,

    The operating input range of the LM5007 is 9V to 75V. The converter can meet your requirement to operate between 10V and 18V. If VCC UVLO is 6.3V, then VIN will be slightly above that based on the VIN-to-VCC dropout of the VCC bias regulator.

    Regards,
    Tim
