Part Number: TPSF12C1 Tool/software: Hello I have to develop a Switch mode power supply, with multiple outputs. Each output needs its own reference therefore I was thinking of a flyback topology. The output requirements are 24vdc 10A: 36 Vdc 0.5A: 5Vdc…
Part Number: TPSF12C1 Tool/software: we are working on EMC passive standard filter for power board (3.7KW max).
power board is connected to main line 230VAC @ 50Hz (MAX input current 15A rms) and use several half-bridge inverter that works with switching…
Part Number: TPSF12C1 Tool/software: First, in the EVM, SENS1 is connected to N, but in the IC schematic it is connected to L. Which is correct? Second, in the CM Choke impedance parameter part of the TPSF12C1 quickstart calculator, the NC core has to…
Hi John,
Inject capacitor cannot be increased to that high value. It cannot be beyond 22nF in the system. You should probably use other knobs to fix the saturation - maybe regulator side Y-caps. Could you please try this and share us the plots? we would…
Hello Niu,
In the simulations that you are running, you have to look at the noise ripple at the grid level by connecting a LISN as shown below
We recommend plotting EMI spectrum on the grid side to look at how it improves when the device is OFF to device…
Hello Fukunaga,
Yes, the architecture is based for a two-stage filter. two CM choke coils are needed.
Yes, the device has inherent protection features for robust design – Withstands surge of 6 kV (IEC 61000-4-5) with minimal external component count. Please…
Part Number: TPSF12C1 Tool/software: Hi Expert,
My customer using this part of design tools.
They curious two section parameter then want to know how to fill it the right answer as their currently design.

I checked my settings and they are the same as yours, but it still can't converge. However, I found a way, which is to set the cycles before launching POP higher (200). If anyone has this problem, you can try my method. Thank you.
Part Number: TPSF12C1 Tool/software:
Does TPSF12C1 work with 9 ~ 36V DC power?
If so, what is the neccesary changes need to be made in order to do so. The datasheet only have AC/DC example
Thank you
Hi Naresh,
Do you have any update?
I will also add a supplement to [Question 2]. If the INJ waveform is saturated, the following measures can be considered. • Increase the capacity of the Y capacitor (regulator side) to a value larger than the value currently…
