Hi,
I am considering using the TPS6124x as a booster for supplying an audio amplifier.
The power source is a typical Li-ion battery, but I require a 5,5V output rather than 5V.
Looking at the datasheet it looks lke adding an external resistor in series with the FB pin, from the Ouput Voltage pin would allow one to slightly tune up the output voltage since the maximum voltage on the output pin is 7V anyway.
The internal feedback network resistor values for R1 & R2 are not mentioned but I assume they would be in the 100s of KOhm.
Can Ti supply these values please, including the internal band-reference voltage ?? Would there be any potential issues with this increase in voltage to 5,5V with regards to correct booster operation ? Just wondering ....
Regards,
Michael
