Hi Dennis,
Sorry for the late reply. About your questions:
1:The 1kHz fFFz is designed for large Cout with electrolytic capacitor on the output. I don't know your part number on Cout, but taking Murata GRM188R61A226ME15D as an example, 22uf x 2 means 11…
Part Number: TPS61023 Hello,
Is there a inductor L1 value design method or value VS output current table for reference?
If I select a 2.2uH inductor, how much the rated output currrent?
Thanks.
Part Number: TPS61023 We made a following schematic. On giving Vin = 4V using battery, Vout was 5.06V as expected. Load is very light and should be in few mA. We are just powering MCU.
Now the Vout is at~ 1V. What could be caused ?
We didn't touch anything…
Part Number: TPS61023 I recently purchased this chip and am struggling to determine where pin 1 is. I believe the orientation has something to do with the long strip on the left hand side, but I want to be sure before I proceed.
This is what it mentions…

When the low-voltage 2.1V power supply is used, we test the SEM performance of B256 and find that there is an obvious spur at 1M. After investigation, it is found that the Boost switching frequency is transmitted to our PA device…

I don't want to use EN pin. Can it be tied to Vin Pin so it is always in PU state when Vin is applied ?
if yes, Please also suggest suitable Resistance value between EN and Vin pin. Is 2kohm Enough ?
Thanks
Part Number: TPS61023 Other Parts Discussed in Thread: TPS61022 Hi,
Need design review of the below design:
VSYS can vary between 3.3V to 4.2V. Maximum output current can be 5V.
Need the output supply clean and with low noise.
Also, trying to send…

Hi TI Team.
I am designing a board where I use the TPS61023 boost converter. Input = 3-4.2 V. Output = 5V at 1A.
The connections are the following:
As you can see, 5V DC-DC Converter (TPS61023) can be powered from the internal…
Part Number: TPS61023 hi expert,
my customer will use TPS61023 in hot-swapped application and they are afraid that the voltage spike will damage the chip.
Does our device have hot-swapped application and do u have any advice ?
the customer also wants…
Part Number: TPS61023 Other Parts Discussed in Thread: TPS61299 Hi expert,
my customer want to use TPS61023 to work in this condition(Iomax=2A). Is TPS61023 suitable in this case or do we have a better solution? thanks! (1)4<Vin≤5V, Vo=5.2V (2)5V<Vin…
