Part Number: TPS63900 Dear Team
Good day!
I had check the tps63900 datasheet (Rev.D) and found some contradictory information . please correct me
In the datasheet , chapter 6.3 ,it shows the output current is 0.4A(Max) , but from the Figure 8-2 to Figure…

Hi there,
I'm working with TPS63900 and developing a new board where the EN pin can be controlled by a DIO (GPIO). The expected behavior is the following:
a. if the DIO is at high impedance state , TPS63900 is enabled
b. if…

Hello,
I'm starting a new board and a high efficiency voltage regulator is needed with the following main specs: - Vin [2V - 3.7V] - Vout [3.3V] - Iout [10uA - 400mA]
I was tending to…
Part Number: TPS63900 Hi team,
My customer is considering to use the TPS63900. Could you please help with the questions below?
When the following recommended parts (L, C) in the d/s are used L: DFE252010F-2R2M, Cout : GRM187R60J226ME15 Cin : GRM188R6…
Part Number: TPS63900 Hello TI Team,
We have designed 3V(1.8V to 3.2V range) LiMnO2 based Battery operated product which uses TPS63900 Buck-boost convertor 3.3V to supply system SoCs.
The Overall system Active current is 30 to 50mA during Active mode…
Part Number: TPS63900 Hi team,
My customer designed this part but they would like to use 1uH inductor.
So they need our advise is it ok or not?
Or is there any concern or criteria to design 1uH inductor?
In our EVM and datasheet, we use 2.2uH for example…
Part Number: TPS63900 Hi TI Team,
We have used TPS63900DSKR Buck-boost convertor for one of our Lowest power 1S2P LiMnO2 battery operated product.
Our input requirements is 1.8V to 3.25V and used TPS63900DSKR Buck-boost convert which convert it to 3.3V…
Part Number: TPS63900 Hi team,
My customer is using our TPS63900 and face some failure at low vin.
If vin= 2.1V , the Vo_3.0V can’t work.
If vin=2.2V, the Vo_3.0V can work. And then I change the Vi=1.8V, the Vo_3.0V still can work
Customer guess…
Part Number: TPS63900 Hi,
It's my Schematic, it can't work Vin=2V/ Vout=3.0V.
I guess the issues that is Venable timing so that I change C1=2.2uF, R1=40kohm. the td(POR_=40.8ms refer the measured wave form/ yellow=Vin/ red= Ven/ Blue=Vout))
It…
