Hello,
I am working with the TPS92411 in a very space constrained application which means that the space taken up by the LED capacitors is at a premium.
The design calculator comes with the recommendation of a 15% current ripple and the EVMs have a listed current ripple of 23 % at 30mA in the 230V EVM and 36% at 65mA in 120V EMV.

Is there any additional documentation on the influence on the system operation of reducing the capacitor than what is seen in the current ripple?
Also are the main concerns for this value dealing with the potential of flickering or strain on the LEDs by higher currents that might result from a large current ripple?
