I'm using the TPS61175 in the layout shown below. The goal is to take an input of about 7V and boost it up to 12V. However, the output I'm getting isn't consistently 12V. When I push 7V through the circuit, I get a nice steady output at about 11.9V. But, after about a minute, the output voltage will drop and will match the input voltage (i.e I'll get 7V at the ouput). If I increase the input voltage a little bit, then the output will jump back up to 11.9V briefly, but will then drop again to match the input. Any advice as to why this is happening is appreciated!
