Part Number: TPS56339 Hi all
My customer is working on a design with these specs:
Vin=12V ... 18V, Vout=5V, Iout=1A
and he wants to use a 15uH inductor.
What is the inductor saturation current he should choose ?
And do you have general guidelines…
Part Number: TPS56339 Dear team,
In the SPEC, Maximum current is 3A. But High side current limit typical is 4.7A (Low side is 3.6A). How dose that maximum current be calculated? If our product output current is 2.1A, is OCP still 3A ? Is that possible…
Part Number: TPS56339 Hello,
I have tried to follow the recommended circuit layout as closely as possible.
I am using the TPS56339DDCR buck converter in a custom circuit where circuit is design for 19V to 2.00V @ 4A with WEBENCH Power Designer. But…
Part Number: TPS56339 Other Parts Discussed in Thread: TPS563249 Hi E2E,
I find the reference design of datasheet which R3 is 20R. (P.14)
Is resistance value too large? I concern that had short circuit issue.
(BTW, TPS563249 datasheet 1st version…
Hi,
Great to hear this issue was fixed . Please let us know if you have any other question . Thanks .
And based on our previous short test on TPS56339, IC may damage only happened when SW short to VIN .
BRs,
Young
Part Number: TPS56339 Hi Sir,
My customer asked questions for buck,
Would you pls kindly advise how to choice a "good" buck? what spec./performance is important?
And how do you verify a buck converter design is good or bad?
Thanks, Ian.
Part Number: TPS56339 Hi,
I plan to use this chip to stabilize the output voltage at 12V. The input voltage can be between 11.5V to 14V. I want to know what the output voltage will be when I provide 12V/11.5V input voltage respectively? Can the high…
Part Number: TPS56339 Dear expert,
My customer use TPS56339 for their 12Vin to 0.8Vout@3A application.
But we face to higher output voltage ripple now.
According to datasheet EQ10, we recommend this application with lower than 1.6uH inductor.…
