UCC28950: UCC28950 dead time setting

Part Number: UCC28950

Hi, team. It is nice to find you all here. I have one question about how to set the dead time of UCC28950. If we connect ADEL to GND, the minimum dead time set through DELAB and DELCD is 250ns. Now I want to set the dead zone time at around fixed 150ns. Refer to fig.48 and page 56 of the manual to pull ADEL to VREF through the resistance network.

  • May I ask if ADEL can only be set at 0.2v or 1.8v?
  • Can I set it between these two values? Will it increase chip losses?
