This circuit was suggested by National Semiconductor and is present elsewhere on this site. The LM2575 is not very common today and should be mounted on a heatsink.
The purpose of this circuit is to re-trigger slow scan circuits used in the 1980s on low frequency...
In the previous circuit (CB15632E) the steps just go up. To obtain ascending and descending cycles...
This circuit is from an old Japanese documentation from the 60s. The circuit uses transistors from...
