CSD95490Q5MC: DC Tolerance over Temperature

Ellwood Lane
Prodigy 10 points
Part Number: CSD95490Q5MC
Other Parts Discussed in Thread: TPS53622

Tool/software:

Hello,

Can you help me compute the DC tolerance over temperature for CSD95490Q5MCT w/ controller TPS53622ARSBT?

Normally I see that tolerance spec. in an integrated power module datasheet, but I don't even see a range in either CSD95490Q5MCT or TPS53622ARSBT?

What are my next steps here?

 

Thanks,

Ellwood Lane

    Hi Ellwood,

    Thanks for reaching out.

    The accuracy/tolerance of the output voltage in case of the controller TPS53622 (or in general with multiphase controllers) is directly dependent on the DAC voltage.

    In the controller's datasheet, we have provided the DAC VSP tolerance in the section 4.6 References: DAC and VREF. The data provided their is the worst case across temperature range specified in the datasheet.

    As shown below in the snapshot below are the data you are looking for. The typical number is +/- 0.5% (for 5mV DAC) for voltage range provided in the table.

    Let me know if you have any further questions.

    Thanks & regards,

    Abhishek
