i have an application powered from lithium battery (3.6v).
The TPS61251 is programed to 3.2v output.
The logic bhaind this design is when the battery new & in warm wheter the 100% duty cycle mode is selected, and the output will track the input.
In cold wheter or old battery the TPS61251 will boost the output to 3.2v.
I have a noise problem (like switching noise) only in the 100% duty cycle mode, the boost mode is o.k.
Any idea ??????????????
I have a current limit resistor of about 0.5A, but the current is far less & there is no problem in the boost mode (supuse to draw more current).
I prefer the TPS61251 on the TPS61252 becuase is snoze mode for very low output current.
