Other Parts Discussed in Thread: TPS61030
Hello!
Currently I am using TPS61031RSAR (Fixed 3.3V output version), but I want to add an option to use the adjustable version TPS61030RSAR with R3=2MOhm 1% and R4=360KOhm 1%.
Can I mount R3=2MOhm and R4=360KOhm directly with TPS61031RSAR (fixed output version)? Does the FB pin of TPS61031RSAR connected to anywhere internally? I understand that there are internal resistors for fixed output version, the external R3 and R4 will potentially parallel connected with these internal resistors if FB is connected.
In this way, in the BOM the chip would have two options: TPS61031RSAR and TPS61030RSAR. Then both would have R3=2Mohm and R4=360Kohm. Is there any risk in doing this?
Thank you,
Sarah
