MP3301GJ-Z feedback pin tolerance

DC-DC Power Converters

Hi, please can you let me know what is the tolerance on the feedback pin of the MP3301GJ-Z. The datasheet only mentions that the feedback voltage is 200mV with no tolerance stated. Thanks

Hello @ashish.malhotra ,

Thank you for posting your question in the MPS Technical Forum.

The absolute maximum voltage that can be feed in the FB pin is 6.5V.
This is shown in the datasheet in the Absolute Maximum Rating section, page 2.

In here it is stated that All Other Pins (Including FB) have an operating range of -0.3V to 6.5V

Hi Edgar, thank you for the reply. What is the tolerance on the EN Dimming threshold?
Kind Regards

Hi, adding further to this, even when the enable pin was less than 0.4V, the driver was still ON. With 0.15V on the enable pin, the SW pin voltage was 8.6V.
