Part Number: TPS552872-Q1 Other Parts Discussed in Thread: TPS63020-Q1 , TPS552892-Q1 Hi Expert,
My customer is using TPS552872-Q1 as a buckboost to output fixed 3.8V, without current limitation, as shown in the following circuit: Can you please help confirm…
Part Number: TPS63020-Q1 Hi
I have a simple question.
This device has a average (inductor) current limit in the high side (buck)switch.
So that , we can estimate a current limit as following at each mode,
at Boost : Iave = Eff * Isw * Vin/Vout
at Buck…
Part Number: TPS63020-Q1 Other Parts Discussed in Thread: TPS63020EVM-487 Hi
Our customer are going to estimate the start up time.
However there are no specification of the delay(startup) time on the datasheet.
How can we estimate the following delay or…
Hi
We have a inrush current problem.
And we have some question about current limit operation at startup. On the datasheet, it is mentioned as the following.
Q1. As it is mentioned, the current limit ramp up from an initial 400mA. However at Figure 17…
Other Parts Discussed in Thread: TPS63020-Q1 Hello,
In the datasheet Figure 11~17 of TPS63020-Q1, there are the Load Transient Response, Line Transient Response and Startup After Enable data on the condition of PS/SYNC = High(Power Save Disabled).
Could…
Hi josh,
that is a good point.
I agree that there should be only one zero/pole setting but not two different ones for TPS63020 and TPS63020-Q1. But i think feeddorward is not necessary and you can reserve a cap in parallel with R1 only.
For TPS63020-Q1…
Hello Moritz,
Thank you for the response!
Please let me know the efficiency of TPS63020-Q1 for Vin 1.8-3,7V, Vout=3.3V, Iout is 0.7A.
Please let me know if you would need any other inputs
Part Number: TPS61378-Q1 Other Parts Discussed in Thread: TPS63020 Hello, we are going to use both of Auto PFM and Forced PWM modes of TPS61378-Q1.
I can't find any description in datasheet on how to switch between these two modes correctly.
Have we…
Part Number: TPS55340-Q1 Other Parts Discussed in Thread: TPS63020-Q1 , TPS55340 Hello, I wish to use the TPS55340-Q1 in sync with other supplies (TPS63020-Q1), which accepts a sync frequency of 2.4MHz +/- 200 kHz. The TP55340-Q1 would work for my application…
