Part Number: TPS5420 Tool/software: Equation 26 for ripple, what are the units of R and C? Is C in uf (100) or 100e-6?
If R is in ohms and C in uf (e-6), (tmax/tmin+tmin/ton) is >1 which makes the answer negative and ripple very small???
Part Number: TPS5410 Other Parts Discussed in Thread: TPS5420 , Tool/software: Hi team,
I was using TPS5410 but the inrush current was larger than expected and I am thinking of changing to TPS5420. Is there any problem if I use exactly the same peripheral…
Part Number: TPS5420 Tool/software: Hello TI-Team,
could you explane, why the value of max. output voltage BOOT to PH has changed from 10V in datasheet Rev. D to 6V in datasheet Ref. F o page 5?
I have implemented the recommended boost caparitor of 10nF…
Part Number: TPS5420 Other Parts Discussed in Thread: TPS2375 HI
When setting the TPS5420 to have a 34V input voltage and a 12V output voltage,
you may experience inrush current during power-up.
Is there a way to eliminate this?
Robert,
Thanks for the explanation. So, with these changes, the part new should perform exactly as the old part did and should be a drop-in replacement, correct? Will there be a way to identify the smaller die? How can I get samples of this to test?

Part Number: TPS5420
Hi,
we are using TPS5420 in 6 applications to step-down 24V from a power supply to 5V. The TPS5420 works in all these applications without any problems for many years. After receiving PCN#20240424000.1 I checked the BOOT to PH voltage…
Part Number: TPS5420 I am adding a capacitor (0.01uF) on the ENA pin to pass the EMC surge test.
Any implication i should be aware of by adding the CAP on the ENA pin?
What is the voltage rating of the CAP i should use?
