Hi Team,
I asked a similar question before. https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1252784/tps61163a-duty-input-resolution/4755790#4755790
And below is our condition.
- IFBx = 1.229V/615k*1030 = 2.05832mA
- 1wire, 16 -> 2.05832*16/511 = 64uA = IFBx (IFB1+IFB2 = 128uA)
Below is the 124pcs histogram that we measured in above condition. The range is wide.
We would like to check with you about below items.
- Do we have spec for minimum IFBx current include 9bit One-Wire Digital Interface?
- What is our minimum IFBx current can be guaranteed(100% duty, 1 1111 1111)?
Regards,
Roy
