Part Number: TPS62843 Dear Team,
We are using TPS628438YKAR for project , however the surface belongs to fiber molding.
In case the fiber so that AOI manufacturing is tough to identify where pin1 should it be after SMT IR reflow.
Do you have any suggestion…
Hello Minghan,
Apologies for the delay response.
Minghan Dong said: You mean add a 1mF cap in parallel with the digital meter as shown below?
Yes, your understanding is correct.

Hi David,
I was OoO for a couple of days and hence the delay to reply.
For TPSM828301, I ch ecked with the designer and here's the feedback. In theory, this method should work but it is not a recommended method because it will probably result in positive…
Part Number: TPS62843 Hi,
I use the buck TPS628438 to transform a 5.4V input to 3.0V. Input comes from a 0.47F super capacitor, so rises very slowly. I would like to enable the buck when I reach around 3.3V/3.5V, to be sure to have 3.0V at the buck output…
Part Number: TPS62843 Hello,
I wonder if a resistor is needed between VIN and EN, since internal FET driven by UVLO/Thermal Shutdown will pull the line directly to GND in case of failure event:
In typical application shown in WEBENCH, VIN and EN are…

Hi Team,
below are several questions.
1. can TPS62843x support 2.2uH inductor? Or it can only support 1uH as datasheet mentioned. If it can support 2.2uH, will eff be improved?
2. If Vout is higher than Vin, that is, there is power…
Part Number: TPS62843 Hi Team,
below are several questions.
1. is there line regulation accuracy on Vout?
2. is there load regulation accuracy on Vout?
3. in datasheet, there is load transient test, what's the slew rate of load change, 1A/us?
Thanks…
Part Number: TPS62843 For a 1.8V rail, appears either version would work. Which would be the best?
Any differences between the two? Even a mere 1% efficiency over the other would help us out here.
Thanks!

Dear expert,
My customer considers TPS6280x or TPS62843 for their system. They have concerns that they are not pin compatibility since size seems not to be same exactly. I think it is p2p, but is it correct?
Part Number: TPS62843 I am trying to simulate the component TPS62843 that my customer is planning to use, but I cannot find an equivalent HSPICE model to perform these simulations.
the syntax is quite different for PSpice vs HSpice.
I understand from…
