Part Number: TLVM13620

Tool/software:

Hi,

We are using TLVM13620 for generating +5V and - 5V.Input voltage is 12 V. 

Output current requirement is 1 A/output.

Kindly review the attached schematic and provide the feedbacks.

    Hi Ashish Ji,

    Some comments:

    1. Ensure CVcc is a high quality capacitor (Eg: X7R) for good stability across temperature. 

    2. For the 5V design - you may want to depopulate the Cff (8.2pF) and check the performance during transients. It should be fine without the feedforward capacitor for most use cases. 

    3. Also ensure the input and output capacitors are properly rated for the max input and output voltages. 

    Otherwise, the designs look good and in accordance with the typical application schematics in the datasheet. Please ensure you follow all layout guidelines while designing your board. 

    Thanks,

    Best Regards,
