Build your own switch mode voltage regulator for your Commodore VIC 20. Replace the obsolete LM323K.
To reduce the current in my Commodore VIC 20, I decided to change the LM323K linar regulator with an switchmode voltage regulator. I start a small project and create the schematic in KiCAD and order the PCB from JLCPCB. All the components are in surfacemount and it was easy to essably them by hand in my lab.
The switch-mode regulators are open hardware now! You can dowload the gerber files from Github:

This is a switching voltage regulator for replace the obsolete LM323K. It is a synchronous buck (step-down) converter. It provides an output voltage of 5 V. The input voltage can be 4,5 to 24 Volts with a continuous current of 3 amps! At room temperature, it does not need a heatsink! The switching voltage regulator operates with a frequency of 500kHz. This device has the same shape as the original TO-3 package. The TO-3 package was used in old devices like game consoles, computers from the 1980 and pinball machines. Therefore you can use this switching voltage regulator to replace your old linear regulators and prevent from damage your old machines. Extremely low ripple and noise! The Pins and the surface of the device are gold plated. The design of the regulator was done with precise calculation and test in the lab. The pcb traces was done to meet the radiation and emission regulations!
Features:
Output Ripple (20MHz bandwidth) with 12V input and with a current of 0,5A: 15mV p-p !!
Wide input range from 4,5 - 24 Volts DC Fixed output voltage of 5 Volts DC
Efficiency up to 96%!
Voltage drop from no load to full load: less than 0,95 %
Low Profile
Short-circuit protection and thermal shutdown
Shielded Power Inductor
Music: By masterdrwho
The Switch mode voltage regulator in TO-3 shape you can build yourself! I put all the designe files on github:

because: the future is open source!!
