LMZ14203H: LMZ14203HTZ/NOPB

Part Number: LMZ14203H

Tool/software:

Hi Team,

I am using LMZ14203HTZ/NOPB to convert VIN=12V to VPUT=5V and as per the data sheet VIN (8-42v) , COUT 100KOhm bigger in package size.

Additionally RON=100KOhm, RFBB=6.49KOhm, RFBT=34KOhm.

Can you please help me to share the reference schematic that converts 12V to 5V.

Regards,

Mateer Bhat

Hello

I am afraid I don't understand your question.

Are you saying that you are not getting the correct output voltage ??

Thanks

Hi Frank,

Yes i am not getting the correct output voltage.

I have attached the schematic, can you please check and confirm whether the resistor values are correct?

Hello

Your feedback divider seems to be OK.

What output voltage are you getting ??

Try to short out the 200k resistor R3.

You may also want to double check your design with Webench.

Thanks
