Part Number: TPS563208 Hi Team,
What if the Vout of our TPS563208 has existing voltage(nearly 1.5V) from other system side, but our device hasn't been enabled. What's the potential risk for our device?
Best,
Stanley
Hi,
Here is what I am stuck with when trying to calculate the output voltage ripples. The slva630a gives the following, simplified equation:
where:
C- output capacitance,
R - ESR value of the output capacitance
F_SW- Switching frequency…
Part Number: TPS563208 Hello,
Thanks for your attention.
We have seen if we didn't put 0.1uf cap near EN pin of TPS563208, when pull up voltage(12V) rise from 0V, the EN will have ringing as figure below, if the 12V rail is not rise start from 0V…
Part Number: TPS563208 Hi, Team,
We have questions for TPS563208. There is Vout > Vin condition on the customer board. Please refer the below blocks.
1. Is it ok to use TPS563208 in this condition?
2. Should they use discharge register? Or should…
Part Number: TPS563201 Other Parts Discussed in Thread: TPS563208 Hi
I read the datasheet of TPS563201. However I do not understand what is the difference of the both device (TPS563201 and TPS563208).
As it's mentioned at the datasheet, the both device…
Part Number: TPS563208 Hi Team,
1. The waveform below was tested from TPS253201, does TPS263208 has the same performance?
2. For Figure34, Vout shutdown because of the UVLO 3.6V, am I right?
3. Does TPS56x20x has output discharge function?
4.…
Hi Mike,
Please share me your schematic and test conditions on the measurement of the output.(Vin/Vout/Iout/L/C etc.)
From the EC table, Vfb of TPS563208 is 0.768V(typ), which is guaranteed by ATE and Correlation test.
Thanks.
Hi all, I found the issue. I found a bug in PCB which leads to additional impedance on PCB via from 4-10KOhm which is the cause of lower voltage on EN pin -> not an IC issue.
