Part Number: LMZ13610

Hi,

I am using LMZ13610TZ/NOPB in my design for 24V to 5V conversion. I have attached the schematics. Can someone please review the schematics and let us know your feedbacks on the same.

Design Requirement:

Vin=24V

Vout=5V

Iout=104657.5V Regulator.pdf

    Hi Shifali,

    Overall the schematic looks good. See my comments below:

    1. Please change the bottom fb resistor from 5.76k to 5.62k to ensure a more accurate 5V.

    2. As your output current is as high as 10A and you haven't clarified your max ambient temperature, please refer to the datasheet section 10.3, Power Dissipation and Thermal Considerations to calculate the required thermal resistance from case to ambient (θCA), and then provide guidance to your layout. In all designs, the junction temperature must be kept below the rated maximum of 125°C.

    Regards,

    Hi,

    Thank you for your response. Maximum ambient temperature will be 40C

    Hi Shifali,

    The max ambient temperature looks reasonable. Please follow the layout design guidelines in the datasheet to ensure a good thermal performance.
