Other Parts Discussed in Thread: TPS630252 , TPS630250 Hi,
Just a quick question: will the TPS630252 also be available as a VQFN package (since the TPS630250 has a product preview for this package)?
Thanks in advance

Other Parts Discussed in Thread: TPS630250 Hello, I do have a problem with using BQ29700DSET as cut off guard for a Li+ battery voltage at 2,8V in combination with TPS630250 Buck/Boost-Converter there are to scenarios which are unacceptable for my circuit…
Other Parts Discussed in Thread: TPS630250 Hi,
Please let me ask about behavior at removing input voltage suddenly. I'm simulating at powering from Li-Ion battery and the low voltage protection in battery is worked and the input voltage is removed suddenly…
The discharge circuit is explained in the D/S. They are fairly low current.
I don't understand why you want to parallel these two devices... The TPS630250 can buck and boost.
Theoretically I would not expect any issues in terms of stability when operating with a huge capacitance at the output. We need to take in account that the converter can run quite some time at the current limit to charge the capacitor.
Did you already…
I'm not sure why you would use a boost. For most of the battery capacity, Vin will be above your 3.3Vout so you would need a buck.
A buck boost, like TPS63050 or TPS630250 are recommended for this.
The device to use is a buck/boost converter, capable of stepping up and down the voltage. Does the device have to support a 2A load? If so, TPS630250 is a good fit. It was recently released in a small 2.5 x 3 mm VQFN package.
Thank you for your reply!
I compared the datasheet of TPS63020 to TPS630250 and as you said TPS630250 is more efficient especially at lower voltage.
In my case TPS630250 Vin 2,5V Vout 3,3V / 2A near 85% efficiency (Figure 11) in comparison TPS63020…
