LM2596: About feedback resistor

Ryoma Ohashi

Part Number: LM2596

Hi team,

For LM2596T-12/NOPB,

is the internal feedback voltage VFB the same as adjustable version which is 1.23V (1.193-1.267 at Tj=25℃)?
What is the tolerance of the internal voltage dividing resistors? Is it 1% for the fixed versions?

Regards,

Ohashi

Hello

We do not specify the internal reference voltage and divider accuracy individually for the fixed Vout versions of this device.

The output voltage tolerance of the 12Vout version can be found in the data sheet EC table.

Thanks
