Part Number: TL494
Other Parts Discussed in Thread: UC3842

Hello,

I want to design SMPS using TI's UC3842 for 12V,10A(Isolated Flyback) also 24V,10A SMPS using TL494(half bridge).I also tried using Webench but could not find UC3842 and TL494 reference design.I want support for schematic,layout and transformer design tool.Also if I could get any reference design for the same it would be of great help.

Hello Shubham

Both these ICs are good choices for general purpose DC/DC converters. They are both relatively old parts and as you found out - they are not supported in Webench.

You will find design information on the TL494 at www.ti.com/.../slva001e.pdf
There is a flyback reference design using the TL494 at www.ti.com/.../slva666.pdf

There is a lot of design related information at www.ti.com/.../login.shtml and I would recommend that you search the articles there for useful information.

Hopefully this will allow you to complete your design.

Please let me know if you need more information.

Regards
Colin
