2) We already procured inductor of 1.5uH…
Hi Tao
Thankyou for the reply
1) About moving the supercap as our output will not good as AP work between 3.8 to 4.2 . So if we use a single capacitor ,voltage will be less and if we use two in series voltage will be more than required . So we cannot…
Part Number: TPS63020
We have a series LED lighting products use the TPS63020 for their driver. And I found almost of this series have the same Radiated Emission issue at around 200Mhz. See below test data:
And use a 4 layer PCB and the layout almost…
Part Number: TPS63020 Hello Sir ,
This is regarding the heating issue of the buck boost convertor (TPS63020) which we are using in our PCB . During testing of our PCB we found that after some time the buck boost convertor heated too much up to 90 degree…
Part Number: TPS63020 Other Parts Discussed in Thread: PMP9769 Hello, I am designing a device using two TPS63020 converters (somewhat similar to PMP9769) and have a couple of questions:
1) In the PMP9769, the VIN and VINA inputs of TPS63020 are connected…
Part Number: TPS63020 I am investigation product field failure and found that one of two TPS63020 devices became extremally hot (+119 C) after 1.5 years of field operation. I checked all related components and they are seems OK and there are no short…
Part Number: TPS63020 Other Parts Discussed in Thread: TPS63802 Hi team,
My customer considers to use TPS63020 and he is asking about difference of load transient response between buck and boost mode.
In datasheet, figure22(buck mode) shows undershoot…
Part Number: TPS63020 in spec 9.2.2.5, it says the bypass capcitor between VINA and GND should not exceed 0.22uF.
however, we had not noticed this comment, and now is using 1uF.
also it works ok, we want to confirm the affect of this cap.
should we change…
Part Number: TPS63020 Hi,
i have been validating the TPS63020 with my design. I would like to know the Power UP and Power Down time when Vsys change?
I could not find in the datasheet. Can you please help me on this.
Thanks and Regards,

Part Number: TPS63020-Q1 Hi,
TPS63020-Q1's datasheet describes 2 kinds of VFB spec in P.5, one is at PS/SYNC = VIN and the another one is at PS/SYNC = GND. Why are the specs defined separately? PLS tell me the reason to separate and the reason why…
