UCD9090-Q1: Multiple part recommendations

Part Number: 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.

 

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

 

Regulators will be managed/sequenced by the UCD9090-Q1.  I plan on using active trim, especially on the 0.88V regulator.

Question: using the using the UCD9090-Q1active trim, plus DC-DC regulator what would be the DC accuracy of the 0.88V?
