Part Number: TPS63805 Tool/software: Hi Team,
Currently, I'm using the TPS63805 buck-boost to stabilize the input 3.3V to output 3.3V,
and the output is facing unstable issue during the power-on (as below pic),
the output appears that it stay at 1…
Part Number: TPS63805 We have designed TI’s TPS63805 “Buck/Boost” Switchmode Power Supply IC into one of our battery-powered (uses 2 AAA alkaline batteries) headsets.
The issue we are having is that in low power conditions (approximately…

Hi, Support Team
We simulation WEBENCH TPS63805, the IC pd is 2.398W
TPS63805.pdf
but If we reference datasheet: PD=(TJ(max)-TA)/Theta JA=(150-25)/78.8 ; Pd=1.58W
wich Pd is correct?
if any suggestion, Please advise me.
Thanks…
Part Number: TPS63805 Other Parts Discussed in Thread: TPS631000 , TPS63802 Which version of the TPS6380x is best suit for a battery powered design that wakes up several times a second and draws ~15mA while awake?
Part Number: TPS63806 Other Parts Discussed in Thread: TPS63805 Dear TI expert
due to TPS63805 shortage, we'd like replace it by TPS63806, the BOM can't change that output capacitor keeps as same as one 22uF capacitor.
our application the…
Part Number: TPS63805 Other Parts Discussed in Thread: TPS63802 Hi support team,
I am considering replacing TPS63802 with TPS63805 to reduce the mounting area. If the only difference between the two devices is the package, is it unnecessary to reconsider…
Part Number: TPS63807 Other Parts Discussed in Thread: TPS63805 Hi support team,
Please let me know differences between TPS63807 and TPS63805. Is it only the following items?
TPS63807 - Output discharge feature when EN is low - 480-µs Tramp for small inrush…
Part Number: TPS63805 Hi，
Could you help me in this case?
The output voltage of the TPS63805 dropped up to 700mV. To improve transient performance, the engineers are looking at Feedforward Pulse Injection Circuit. Below is a screenshot from SLVAEE0. How…
Part Number: TPS63805 Is the Power Good output purely based on a voltage comparison between the VOUT level and the target VOUT level? Or are additional signals used in the logic also? For instance, is Power Good also gated by the enable input?
Thanks…
Part Number: TPS63805 Hi,
We are using the TPS63805YFFR with a 22uF cap at the input and a 0.47uH inductor.
When the inductor is switching, it is causing noise on the VIN capacitor.
Attached is a scope capture of the noise.
Is there a recommended capacitor…
