  Part Number: TPS3808 Tool/software: Hi, TPS3808 has different suffix: G33 and G25. We can put 3.3V on the VDD of TPS3808 G33. How about TPS3808 G25? Can we put 2.5V on its VDD? When we connect 2.5V to VDD, does MR support 3.3V level signal?

  Part Number: TPS3808 Tool/software: Hi, I encountered an issue: pin 5 (SENSE) has 1.8V, but pin 1 does not output 1.8V. Could it be that the 100k pull-down resistor R2M6 to ground needs to be removed? Thanks! Jeff
