Regarding the power system we are designing for our on-going project now, we have some questions with selecting…
in the li-ion input voltage application, i would suggest TPS61230 instead of TPS61030. I guess the input current will not higher than 1A, so you can have a look at TPS61253 series or TPS61252.
thanks

If you just want a working circuit to test, I recommend ordering the EVM. As with any switching power supply, this IC is very sensitive to layout and poor PCB layout can destroy it. The shorts between those pins likely mean the internal FETs have been…
In power save mode, these devices do have greater ripple. You can operate in forced PWM to reduce it.
More input capacitance and/or a lower impedance connection should reduce the input ripple.
But a newer device would likely be better for your system…
To charge 2 LiIon series from 5V you need a boost circuit.
To charge 2S LiIon from 24V you need a buck.
To create 5V from 2S LiIon you need to buck.
The easiest path for a 2S seems to be using the 24Vin to charge the 2S, then buck from the 2S to…
Yes, the TPS63010 could work for all 4 converters needed but I would only recommend it for the 5V to 5V one, as that is the only one that requires a buck boost. You might use a regular boost, like TPS61070 or TPS61253 or TPS61240 for making the 5V rail…
There is a much newer version of the datasheet on our website. Additionally, we have released many new devices since 2003 that are likely better fits for your needs. I would recommend using them over the TPS61020 family. They include TPS61200 and TPS61253…
I suggest you read the guidelines post at the top of this forum for tips for getting you the best support. It is critical to begin the title of your post with the part number(s) so that the correct apps engineer can see it and respond. I recommend that…
