    Chris Glaser
    Most causes of IC failure are layout related. Make sure you have followed the layout recommendations in the datasheet. You can compare your layout to the EVMs.

    The new TPS63060 is very close and is simple. The TPS43000 also almost meets your requirements. A solution that meets your requirements as stated would likely need a dedicated boost converter running off the input to act as a bias supply to another boost converter, TPS61175 for example, configured...

  • Forum Post: Any effective chip for 3.3V -> 9V boost case?

    Gamin Inganela
    Hi all, The following seems like a very common and simple scenario and yet I am unable to find any part or straightforward method to achieve it: Our device will be powered by a single-cell Li-ion battery (thus, 3.0 to 4.2 Volts supply). On the circuit, we have a 24-bit sigma-delta ADC (the TI ADS1252...

    Chris Glaser
    You are welcome to make any mods you like to the EVM. I frequently do this in the lab to build other circuits--lifting pins of components, cutting traces, etc. Just draw the schematic you want to achieve and then label the pin numbers of each component you touch and it goes simply. In the future, please...

    Hi,John-san Thank you for the reply. I would sometimes like to hear one more. Is a difference between TPS61041 and TPS61040 in addition to the contents indicated to the data sheet? (When transposed to TPS61040 from TPS61041, the noise occurred in the picture outputted.) Best Regards, Yusuke...

    Let me ask about TPS61040 and TPS61041. Is the difference between TPS61040 and TPS61041 only an output current value? If there are other differences, please let me know. yusuke

    Chris Glaser
    Ah, yes, the fact that you have a very current limited input supply is a key detail to mention. Some scope waveforms of Vin would confirm that your input source impedance is too high and that you are indeed tripping the UVLO, but that is likely what is happening. The delay on taking the CTRL pin high...
