Two Takes on Making a Tl494 QSPICE Model

My First PWM ic model (TL494ish)

Hi Bordodynov, Thank you for your reply. Apologies for the delay; I’m spending time with family this week and have limited PC access. That’s a very different approach – I like it! It looks like it models the IC more faithfully than mine, which was aiming for functional similarity. I particularly like the use of current sources to drive the output transistors. I’ll definitely experiment with this myself. Thanks, Ed
