SIMPLIS model for TL494 SMPS controller
Introduction TL494 is a widely known PWM controller for SMPS. However, it is an old bipolar transistor integrated circuit and only a few SPICE models are available. The major drawback of SPICE for SMPS design is the duration of the simulation. Nevertheless, other simulations approach based on state space modeling exist. Personally, I use SIMPLIS…

SMD Pixie : 9V Version 0
This idea came from a discussion on reddit post talking about K6ARK’s micro pixie operation. As I never tried doing anything in SMD I though it would be a great project to learn the basics. The schematic is really simple, I just took an already working schematic from chinese pixies and reimplemented it in Kicad…
