TPSM863252: Part recommendations

Matthew Baker

Part Number: TPSM863252
Other Parts Discussed in Thread: UCD9090-Q1,

Tool/software:

I have some DC-DC power regulator needs and I was hoping TI could recommend the best DC-DC non-isolated match. The input will be +5V.

0.88V, 25A, 3%(1%DC accuracy + 2% AC ripple) , step response 9A over 350ns, ramp up time ≤ 5ms.
0.8V, 4A, 3% DC accuracy, ramp up time ≤ 3ms
1.2V, 500mA, 3% DC accuracy, ramp up time ≤ 5ms (maybe an LDO fed by 1.8V)
1.8V, 2A, 3% DC accuracy, ramp up time ≤ 3ms
3.3V, 2A, 3% DC accuracy, ramp up time ≤ 5ms

Regulators will be managed/sequenced by the UCD9090-Q1

Hi Matthew,

Thanks for reaching out. What is the range of 5V?

I am not understanding your question.

We need 5 devices or rails that match the above-mentioned specifications. The input for all of them will be 5v.

Hi Matthew,

I will check your feedback and get back to you next Monday.

Hi Mattew,

Let me clarify, as you know, our device has input voltage range. For example, for TPSM863252 (the part you choose here), its input voltage range supports 3-17V. That's the reason why I also check with you about the input voltage range in actual application. For example. if your input voltage is only up to 6V, I can assign this thread to other teams who will be expert.
