Other Parts Discussed in Thread: LM3409
Hi, We performed the Temperature sweep and Unit sweep for our PGU by DLPC230, and then found something different by comparing the .sweep file of them. We found LM3409offsets present in both sweep files, but they were all zero in temperature sweep files, while they can change with the current limit of all DM coarse combinations In the unit sweep file.
Temperature sweep:
Unit sweep:
Correspondingly, the RGB blanking currents for all DM coarse combinations in the unit sweep are a maximum of 1023.
We believe that the current limit in this case cannot limit the LED current, which will affect the LED life.
Did I not understand the logic behind this? Can you tell me why the algorithm is set up this way? Thank you very much
