LP8866-Q1: question about BOOST LED Driver design tool

Feeney Xiao

Part Number: LP8866-Q1

Hi expert

I have a question about this design tool. what is the Vminboost mean, is that mean while the voltage is higher( or maybe lower) than Vminboost, we think the LED short happen? Is this voltage detected at LED0-5 pin or Vout?

However, we also find that the LED internal short threshold is 5.4V at datasheet.

Hi, Feeney

minimum boost means the minimum voltage boost can output.
