Hi,
In the tina ti file of UCC28070 , there are two capacitors at the output. What was the actual output capacitor??Is it C17 or C18??
How to calculate the RLBoost value for the circuit. Its calculations are not mentioned in the design tool.

Hi Mownika,
C17 and C18 are both output caps, but C17 is only 47nF, so it's essentially acting as a high-frequency filter. What you would consider the dominant output cap is C18 at 100uF.
For Lboost, please see p31, Sec 8.2.2.3 in the UCC28070 datasheet.
