Circuit with a power transistor and control circuit for the transistor has two control units with currents having nonlinear relation to load voltages

摘要

A circuit with a power transistor (T1) having a connection (G) connected to a control (10) and load (D-S) connections. The control comprises two control units with current source (Tq1,Tq2) the controls having current sources (Iq3,Iq4) at the output (AK) which are produced non-linearly from a voltage through a load-dependent current.
