Part Number: TPS63021 Hi,
I am trying to use TPS63021DSJR for converting a litium battery (between 2.5V, 4.2V) to 3.3V and also 5V (while charging the battery) to 3.3V. But i am getting 6.3V output. I could not find why. Here is my schematic and pcb.

Hi Team,
We are using TPS63021 buck boost regulator in one of our design to generate 3.3V from 3V/5V. During FCC Part 15C testing, we observed peak radiation at 318MHz. After isolating the above said regulator we were able to resolve…
Part Number: TPS63021 Hi team,
My customer used TPS63021 as 3V3 regulator for their system voltage. Their efficiency appears to be lower than expected when battery drops to 3V. This is the lowest voltage they will allow but they need 2.4A ( datasheet…
Part Number: TPS63021 Hi Team,
We are using TPS63021DSJT -3.3V regulator in our design.
It is expected to get 3.3V at the output. But, we are getting 3.33V to 3.4V(But Impedance looks fine-6.3K in all the boards). Since it is not an adjustable type regulator…

Hi, The following are the design parameters Vin: 3V to 4.2V (Li Ion Battery)
Vout: 3.3V Iout: 600mA
Following is the schematic and PCB design . Need a review for the same. Thanks! Milind Hardware Engineer PupilMesh Private Limit…
Part Number: TPS63021 Do you have ripple characteristics for this part? Other TI converters typically publish the graph, but not this one.
Does low power enable (PS) pin have to be pulled high for normal operation?
Is VINA supplied internally? The confusion…
Part Number: TPS63021 Other Parts Discussed in Thread: TPS63020 , TPS63802 , TPS63027 According the datasheet the TPS63021 can deliver 3A@3.3V, but with the Webench designer the max allowed output current is 2A. I have also tested the TPS63021, and it indeed…
Part Number: TPS63021 Other Parts Discussed in Thread: TPS82085 , TPS63020 Hi Ti,
I have tested the prototype new design that uses TPS63021 power management IC and encountered some switching noise coming out from the IC and the coil inductor. Specs as…
Other Parts Discussed in Thread: TPS63021 Hi,
I am using TPS63021 Buck-boost converter for my application and I have successfully designed for the requirement. But I tried simulating the same circuit using WEBENCH and its schematics was nearly the same to…
Other Parts Discussed in Thread: TPS63021 , TPS63020 Hi! I'm working with 2 TPS63021 in my design. One, it is for 5V outputs (IC1) and the other is for 3.6V (IC2).
I have problem when the 2 ICs are working. The IC2 works perfect but the IC1 has a short…
