Switching voltage converter for use in electrical engineering, has integrated longitudinal regulator utilized as voltage reference and standard-logic-integrated circuit utilized as control circuit

摘要

The converter has an integrated longitudinal regulator utilized as a voltage reference, and a standard-logic-integrated circuit (IC) utilized as a control circuit. A bipolar transistor is used for limiting current of a switching transistor, where a base emitter voltage of the bipolar transistor determines interrupting current in connection with a resistor. A stabilized voltage that is supplied from outside the voltage converter is used as a voltage reference.
