Other Parts Discussed in Thread: TPS61299
Tool/software:
Dear Support,
We are evaluating the TPS61099 and have some technical questions:
The TPS61099 come with a burst mode under light load condition, and once this mode is entered, the DCDC output ripple voltage becomes very high (~100mV).
In our application, we need the output ripple to be within 30mV even under light load (<5mA load condition). However, the condition to enter and exit the burst mode is not clearly stated in the datasheet.
Could you help to provide a threshold or calculation formular to determine the threshold to enter/exit the burst mode?
The L and C we used is 2.2uH and 2x10uF with output voltage set at 5.5V, and the input voltage is range from 3.5V to 4.6V.
Best Regards,
kpk
