LMZ31710: Mechanical Reliability Related to Temperature Change

Kazuki Itoh

Part Number: LMZ31710

Hello team,

My customer did an X-ray inspection of LMZ31710.
The internal coil appeared to be mounted on the top surface of the IC.
The shape of the case is not rectangular, and looks a little bit special.
My customer cares about the risk of mold breakage due to the coil expansion caused by temperature change.
Do you have any collateral to convince my customer?

Regards,

Itoh

    Itoh-san,

    The LMZ31710 is specified for operating over recommended -40 to 85C ambient temp, with abs max junction temperature up to 125C. The device should be robust within this temperature range.

    Please email me directly with more details on the concerns if needed.
