Other Parts Discussed in Thread: TPS62750 , TPS62080 Hi
I would like to hear about TPS62750.
1. As long as I see figure 8, when output voltage is about 3.6V output current is from 0.6A to 0.7A, is Rlim_U 49.2kΩ at this time?
2. If input voltage is…
Hello,
thanks for your answer ! No, the dashed curve are the input of the system (connected to VIN of the TPS62651).
Please only focused on the red curves (done with the tablet), I would expect a better regulation of the TPS62750 output voltage. For…
Hi Steven,
Your Vin range is less than the Vout. Is this intended? It is ok for the TPS62150, but a boost converter will give you 5Vout with this lower Vin.
No, there is no limit to the SS cap value. Increasing it will reduce the inrush current.…
Part Number: TPS2140 Other Parts Discussed in Thread: TPS62750 , Hi team,
I have a general question about interpreting the USB 2.0 spec regarding current limiting. I see that section 9.2.5.1 Power Budgeting it states that "USB devices shall limit the power…
Yes, that's about right on the 400mA. Your load needs to consume less power than your source can provide.
If you are driving a pulsed load, like a radio, you can store some energy in a capacitor to keep the average power consumption within the limits…
This is usually unnecessary as you have control over how much current your uC draws.
If you're concerned about it, then you could use another TPS62750 for the 3.3V rail too.
The TPS62260 D/S does not have the last sentence in that paragraph.
For your application, the TPS63020 is often used or possibly the TPS62750 which is designed to support large output caps.
