This 90s Motorola circuit from, has current limiting foldback. The power transistor is from the era, and equivalents can be used. The output is 250 V.
With an output power of 1.5 W under a 12 V supply, this circuit makes use of transistors that are...
I got this circuit from Hands-On Electronics, 1988. The American magazine no longer exists, but...
This circuit is from the Motorola Linear Databook of 1990. The values of the components depend on the...
