TL494: TL494 Pspice Simulation Problem

Unal kaval

Part Number: TL494

Hi, I'm practising my electronic skills through Orcad 16.6 and I'm trying
to figure out buck converter designed by using tl494. I've read your
datasheets and buck converter design notes but I couldn't manage to achieve
to get a proper outcome from my circuit. Could you send me your working
version of Buck converter with tl494 in Orcad 16.6 compatible form? It
would be great.And could you send me the schematic and layout as well for I much desire to see it for myself. Thank you.

Hello Unal,

Can you please share your design spec: Input/output conditions, switching freq etc.
I would also recommend going through the TI reference design library and search by power design parameters you will find a wide range of designs with the user guide.
I hope this helps.

I don't know about the exact input range but output is fixed 5V/10A, freq is 20kHz. Page 24 www.ti.com/.../slva001e.pdf in here. I applied the same parameter for everything except for some components aren't in orcad lib, I've used pspice models for them.
