Hi expert,

What's the VIT- and VIT+ for TLV840MADL30DBVRQ1? In TPS3890-Q1, we have a table as below, but I didn't find such kind of table in TLV840-Q1. Thanks.

I guess for 3V version, the VITN=3V, VITP=3*(1+5%)=3.15V? Thanks.

Hi Arie,

That is correct. The worst case VITN would be 3V * (0.98) = 2.94V and VITP would be 3.15V as you mentioned.

Thanks,

Hi Isa,

Thanks for your quick reply. Customer met some shortage issue on TPS389030QDSERQ1. Which part is the best alternative for it? Non P2P is also acceptable. Thanks.

Hi Arie,

Is a separate sense channel required? If not, we can propose TPS3840DL30DBVRQ1. Will this work?

Thanks,

Isa
