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,

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.

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…
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…
