Original question:

TPS62363: Datasheet misdescription about Chip_ID

TPS62363: TPS62363 OUT PUT 0.6V

William Yan

Part Number: TPS62363
TPS62363  lowest Output Voltage Presets is 1.0V.
The chip must be soldered to the board and I2C modified to 0.6V, but the default 1V voltage of the power-on output will damage the chip behind. How can I avoid it?

    In mass production, it is certain that all the chips are reflowed together. It is impossible to weld separately, which will result in weak soldering.

    Hi William,

    thanks for your questions.

    Could you please confirm my understanding below:

    You have two questions:

    1) How to set Vout to 0.6V as the chip which is supplied by TPS62363 is damaged at higher input voltages and

    2) If reflowing all chips together in mass production will have an impact on the soldering?

    For 1)

    I think you are referring to the Vout presets which can be selected through pins VSEL1 and VSEL0, correct? Please notice that you can also configure other (lower) voltage levels through the integrated I2C interface which is operable when VDD and AVIN are present, independent of the state of the EN pin, see section "Enabling and disabling the device" section of the device datasheet.

    2) Is this an independent question? Please help me understand.

    Please let me know whether my understanding was correct and provide further information on 2).

    Thanks and best regards,

    Britta
