This charger for automotive use provides a 0.42 A output current. We find it in an American documentation from the 90's. The transistor must have a heat sink.
A double port MOSFET is used in this circuit, which drives a 100 uA moving coil meter or close to it....
This circuit allows the use of two triggers (inverters or NAND ports connected in this way) to...
This circuit generates signals with opposite phases determined by C1 and adjusted by R2. The...
