We found this circuit in an old publication. The components used are rare today. Accuracy depends on the resistors in the input selection network. The circuit operates from 10 to 500 kHz.
The load current can be adjusted up to about 1 A. The transistor can be TIP32 or TIP42. The...
With this step the motor is energized when the TTL or CMOS input is high. Motors up to 1 amp and...
The diodes on this power supply are 2.5 V x 1000 V. The circuit provides a very high voltage for...
