Part Number: TPS61041

Hi team,

what's the SW voltage range of TPS61041?

In the datahsheet, the absolute maximum rating is 30V ~30V ? is there have mistakes on datasheet?

what's the correct range of SW ? thanks.

Hi Betty,

This should be a typo. The MIN spec should be -0.3V. Thank you for the reminding. We'll update it.

Hi Zack,

one more question. can you provde the SW transients parameters, like below picture? customer need this for internal test.thank you,

Hi Betty,

I'm not sure if we could find this data because this device is RTMed 20 years ago.

What's the output voltage that customer is setting?

Normally if customer's layout is good enough, they don't need to be worried about the SW transient. Please help review the layout for customer.

Hi Zack,

customer have a concern about the SW transients. The TPS61041 is used in mass production project, measured the SW waveform, sometimes, the low level of SW will be -420mV,see the below. does it have risk in application? thank you

Hi Betty,

Can you share the full schematic and layout for me to double check?

Also, to measure the min SW voltage, please change the scale smaller, i.e. 100mV/div.
