Part Number: TPS54239E Hi,
I am using TPS54239E in one of the project design and found out it is very susceptible to ESD. The ESD event causing the MCU to reset very often, is this a known issue? Is there any recommendations to resolve this issue?

Part Number: TPS54239 Hello,
I'm using TPS54239E in a new design.
For a 5V output voltage, the maximum output capacitor total value is 68µF (table 1 of datasheet).
- Does this maximal value includes DC bais effect of the capacitor?
- Does this…
Part Number: TPS54239E Hi,
Due to shortage of MLCC capacitor in the market, my customer would like to change C170 capacitor in their schematics from 0.47U/16V/X5R/0402 to 0.47U/10V/X5R/0402.
Questions they have are:
Will it affect any performance ?
After…
Part Number: TPS54239E Hi
I got questions about TPS54239E from my customer.
・Could you tell me the max Duty cycle of TPS54239E?
・Could I use the inductor of 15uH?
Best regards,
Yokota
Part Number: TPS54239E Hi
Fig10 of TPS54239E's datasheet is the characteristics at Ta=25℃.
Are there the data of any other ambient temperature?
My customer need the frequency tolerance.
Best regards,

Hi,
Which part dose you use? TPS54239 or TPS54239E? TPS54239 is FCCM, and TPS54239E is Eco-mode at light load.
If you want to save the loss, you'd better to use TPS54239E.

Hi Gerold,
I have tried with 2 randomly selected components, TPS54239E and TPS54341 and here the simulation works. I have now actually also simulate the original circuit, but I think the problem comes when I change the load transient parameters. Try to…
