Multiple output DC-DC flyback converter with wide range of input

[Hasan2021]

Hi there,

I am willing to design similar product for diffirent input range, 

Can you suggest any IC that is applicable for muilti output like 5V/3A, 12V/2A with 250-650VDC input?

Lets talk about https://www.infineon.com/dgdl/Infineon-ICE2QS02G-DS-v02_00-en.pdf?fileId=db3a30431a5c32f2011abef4f7f... 

My applicable circuit should be following type. See the attachment.

Hi,

    Thankyou for Posting on Infineon Developer Community. 

I understand that your are designing a Flyback converter with multiple output voltages. 

As rightly pointed out by you, you can go through our portfolio of CooLSET ICs which is targeted for Flyback Controller applications. 

The following are the available ICs in this portfolio, 

QR Flyback Controller IC

Fixed frequency controller IC

For achieving ZVS, you can opt for the following controller IC,

Unfortunately we donot have a complete circuit which has a flyback controller with multiport configuration.

But we do have POL ( point of load ) voltage regulators. Many POL can be connected on the output of a Flyback converter to achieve multi port output. 

The portfolio of POL regulators can be found here. 

I suggest you to look at the following POL regulators that matches your application, 

IR3883MTRPBF

IR38060M

Additional suggestion:

    If the converter in your application is not fixed, then you can go for our PFC+LLC combo controller IC. 

These do have application notes that demonstrates multiport output voltages. Few application notes which matches with your specifications are as follows,

1) Using IDP2303

2) Using IDP2308

These controller ICs are completely configurable to match your application.

Hi Abhilash,

You have provide broad range of solution.

Kindly tell me a specific one. My referance one does not suitable with this design?

Hi,

  Currently as mentioned in my previous response, we dont have a reference design for your application. 

But we do have it in our PFC+LLC combo controllers. The link for this has been provided in my previous response.

Hi,

    The demo board DEMO_5ASAG_60W1 is a good match for your requirements.
