Boost_Converter_LM51231_Design.xlsx
Dear Moritz, you can find attached the excel requested. Consider that linked to the Boost output there are 6 buck converter LM65645 each with 50uF Cin. So total capacitance between Vout Boost and GND is 650uF. …
Hi Lucas,
Cout value is to keep low ripple. It is a high value cause of the high DC current and low Vout (4V/6A). For a Flyback in DCM (LM5185), Iout ripple has a high harmonics content compared to a CCM Flyback. Calculator spreadsheet sets Cout to…
The capacitor charging current should be 2.5A.
The completed document is attached.

Hi Patrick,
I am not that famialr LM5160 with the flybuck solutions but I do have a design tool that may be of use. I suggest you also copy and post in the non-isolated dc/dc forum as the LM5160 is supported by 4380.Flybuck Flyback Calculator.xlsx that…
8863.Flybuck Flyback Calculator.xlsx Hi John,
I have attached the flybuck tool which may be of use. Just to let you know that I moved your post to the non-isolated forum as they support the TPS40210.

Hey!
I am reading the code for the project "BLDC_Sensorless". The COMTN_TRIG-Macro is used for determination of correct time for commutation.
I read…
Hi DAN,
In addition to Mr. Manish Sir, you also go through the pdf attached by me. In this, you got all the modules which use to implement the above control loop. Still, you have some difficulty please give me the reply.
Now the sampling time of 1…
Dear Moritz,
we have seen that our Iout is very low, near to 70mA supplied . Our Boost enters in CCM only for Vin< 3,8V.
We have to change inductor with 250-350uH one.
Moritz said: Please try 5k, 200n, 1n.
Considering your suggested compensation…
