Please provide amplifying information for the sin(θ) term in equation 28 from the LM3444 datasheet (SVNS682D), page 20. Specifically, what is the term accounting for when determining minimum voltage present to drive the LED stack. The next equation (29) gives an example with the value of 135° for theta but does not discuss where the 135° was determined or why this value is used.
Thank you for looking into this for me.
Sincerely,
