Other Parts Discussed in Thread: TPS62147, TPS54202
Hello Team,
My customer is using LM27342 with 12Vin, 10Vout, at no load condition, the output loss regulation can't keep stable at 10V, I noticed a min load is required mentioned in datasheet when output is greater than 3.3V.
They are using the inductor is 2.2uH, at this condition, 20mA is required then output can be regulated. here are customer's questions:
1. Can you tell what's the reason of LM27342 min load is required?
2. How to determine the 20mA is good enough when considering MP? How to know the required min load in every design condition?
3. Min load 20mA for customer is too high, which similar part you can suggest to instead of LM27342?
Thanks,
Martin
