WEBENCH® Tools/TLV61046A: TLV61046A with unstable load

Part Number: TLV61046A
Other Parts Discussed in Thread: TPS61071

Tool/software: WEBENCH® Design Tools

Hi team,

I am using TLV61046A for OLED application, input voltage 1.8~3.0V(two alkaline batteries in series) boost to 12V

Since the current consumption of OLED seems to be unstable, the output voltage of TLV61046A is also unstable and is affected by other parts. Specifically, there is noise in the preamplifier next to it (about 107Hz). Please tell me what to do。

Schematic as below
