Part Number: TPS40304A Other Parts Discussed in Thread: TPS40304 , Hello,
We've a PCB design powered by a TPS40304 buck controller.
We are considering to replace it by TPS40304A, but I don't have clear the differences... The only differences I found…
Part Number: TPS40304A Hi,
We use TPS40304A to design the power supply.Input voltage 3.7V, output voltage 1.8V, no output voltage, what is the reason?We produced 1,000 units, and about 30 of them had this problem. 附了实际参数的原理图(1).docx
Part Number: TPS40304A Other Parts Discussed in Thread: TPS40304 Hi,
Good Day. I have a customer who is working with TPS40304A. Please see below the query of our customer for your reference. Thank you very much.
We have multiple output power supply consisting…
Part Number: TPS40304 Tool/software: WEBENCH® Design Tools Hi Sir
Why I calculate Rs resister is different webench simulation? My cal is Rs is 1.74K, webench is 3.4K. and by the way, may we know what's different between TPS40304 and TPS40304A?
My…
Kang,
I think your initial e2e question got lost in the wrong forum. Since you do not need PMBUS for what you are proposing to do, would recommend the LM27403 or TPS40304A. Please note in your scheme you are making the dc/dc change its voltage to modify…
Ramgopal,
Your assessment of the bulk decoupling required is correct. You must calculate the required amount and validate it. The Hardware Design Guide (SPRABI2) discusses this calculation.
This bulk capacitance will affect the control loop on the power…
SI,
Please see the attached presentation. It was originally prepared for the LM10010 which was later superceded by the LM10011 which has higher precision. Please also see the many E2E posts discussing the LM10011 and TPS56121 with C667x and C665x.
