Fly Buck Design
Turns Ratio
Additionally, in terms of an excel calculator, I found…
Yes, you can have a step up on your coupled inductor you just want to make sure you keep it low. A rule of thumb I have heard in the past is keeping it below 2, preferably, 1.5.
In addition, you need to make sure peak primary current limit isn't hit,…
Elena:
Pl see attached.
I am using web bench values- but that is for 1 output.
We have 3 outputs in addition to the buck output.
The spreadsheet attached will show that.
Thnx.

Hello,
a 1:3 turns ratio is not advised for FlyBuck topology. Recommend an inverting Buck boost on the primary, setting Vout primary to -15V out and use a 1:1 turns ratio to get 15V out at 0.5A. With a 6V input voltage, you should be able to obtain 0…
Part Number: LM5160 Dear Team,
We use Webench and Excel tool for the design, but got different inductance value.
Can you help on checking it?
Webench:
VinMin: 35V
VinMax: 58V
Vout1: 10V, 0.05A
Vout2: 5.5V, 0.6A
User Preferred Frequency 300kHz
L=121.9…
Thanks
I have reviewed your article.

Actually I wanted +/-5.5V at the outputs to supply TPS7A series LDOs (I have set the TPS7A LDOs at 5V, 3.3V and 1.8V) and if you see I set the outputs at +/-8V in the Excel file bcoz I'm concerned…
Part Number: LM5160-Q1 Other Parts Discussed in Thread: TINA-TI , , LM5160 Hi team,
My customer wants to construct isolated DCDC with below condition.
- Vin range : 6V(min), 12V(typ), 17V(max)
- Vout_iso : 12V
- Iout = 400mA (max)
- Switching Frequency…

Yes we are in the process updating it.
In the meantime you can use this one temporarily
Thanks
