This circuit is from Ferranti documentation from 1967. The operational is of the time, but the configuration is valid for modern equivalent components, including higher current capacity.
This circuit, found on Motorola's Linear Interface ICs uses the MC1536 as a driver for a 36 W or...
In the figure we have the conventional configuration to use a triac to control a power load from...
We find this oscillator in a 1980s documentation. The frequency depends on the crystal and the...
