TPS25946: No VOUT

Part Number: TPS25946

Hello,

The IC does not output the Vin voltage of 23.3V.

If circuit is bypassed by placing R126 or R98 then the 23.3V is present

Is there any extra consideration for UVLO, OVP, ILIM, DVDT or ITIMER for when Vin is 24V?

Thank you

    Hi Roberto,

    This is device has recommended max rating of 23V. It is not meant to be used at 24V. Also OVLO threshold is 28V which is above abs max rating of device. OVLO should be less than equal 23V.

    Is device damaged?  Can you try with lower voltage ? maybe 20V. 

    Regards
