Other Parts Discussed in Thread: LM3445,
Dear all:
1,We have a line lamp project requirement, and we are going to use LM3445 to do it.I have seen TI's lm3445evm-695, and I think this circuit is relatively complex. Can you explain the functions of each circuit in the DEMO (the position of the red box is drawn)?
2,The capacitance of lm3445evm-695 is 22uF.If the grain filling capacitance increases, does it affect the output?There is a formula for the relationship between capacitance and output voltage and current
3,The output dimming line lamp power is not the same (such as: a total of three line lamps in parallel, the output voltage is 42V, the current is 160MA, 320MA, 480mA), what should LM3445 do to ensure the dimming depth of three lamps consistent?
Thank you!
