Other Parts Discussed in Thread: TPS61022 , TPS61094 , TPS61235P Hi.
Need help looking for a suitable part for a new design.
The requirements are as follows:
- No BGA less than 0.7. QFN, DFN preferred
- VIN = 2.8V to 4.2V.
- VOUT = 3.3V. to 3.7V
- IOUT >3…
Hello Zack,
Thank you for the response.
You understood correctly that under resistive load TPS61023 gives us up to 2A, therefore, the converter seems to be functioning ok. Our application plans for about 1.5A so even though 2A is at the limit, it should…

Hello engineers,
I'm currently developing a PSU for a low-cost portable equipment, I've drawn a preliminary schematic using the three chips in the title; please take a look at the (incomplete…
Hello Daniel,
I would highly recommend looking at the bq25895. It is a very capable charger and it performs full BC1.2 USB enumeration which would handle negotiating power from the source.
Regarding how you are accomplishing the output OTG power I would…
The bq25895 should work for your application. If the part is self turning off Q4, there is a large current spike causing that to happen. Many boost converters are known to pull large current spikes, especially at startup. The TPS61235P has an 8-A current…
Hello,
I haven't actually measured the current draw of the raspberry pi 3 running it's application. The only external peripheral would be the HDMI port feeding video to a TV. Regardless, it looks like the Pi 3 consumes a lot more power than its…
