Thank for your reply.
inductance down to 3.3uH and connecting parallel 47~100nF with R6(1M) my issue is resolved.
I will also attach a TPS61071 pattern, so can you tell me if there are any bad points?
Unfortunately, in this time the pattern…

Let me ask about the production situation of the TPS61071 IC, present the price is increasing and the limited quantity? I am using this component for long term project and mass production. The price increase…
Part Number: TPS61071 HI Team,
My customer now use TPS61071 so as to convert 4V to 5V.
Customer now haven't added load. And found that the output and FB is very strange.
The Vin and Enable are ok.
Customer have made several board, and each board have…
Part Number: TPS61071 Hi Team,
My customer now use TPS61071 to boost 4V to 5V.
Now they haven't added load in their circuit. The measurement value of inductor is 3.99uH. However,customer has 3 board, one is 5V normal, the other two are abnormal, 1.7V and 3…

Part Number: TPS61071 My customer designed attached schematic file based on datasheet parameter P12 formula.
But output voltage shows slightly different against VOUT cal formula.

Would you please adivse how to adjust…
Part Number: TPS61071 Hi
Let me confirm the position of CparR1.
The customer uses R1=820K and R2=91K to get 5V output.
So CparR1 will be needed. Is it correct that the placement of CparR1 like below figure?
