4- Mutual Inductance
... As described before the inductor is a special case of a more general set of circumstances. For the simple inductor the current producing the magnetic effect (‘field’) flows in the same conductor on which the magnetic field reacts. This is self-inductance, and the volt-ampere relation is V1 = L11 dI1 ...

L6920 - STMicroelectronics
... In L6920 the control is based on a comparator that continuously checks the status of output voltage. If the output voltage is lower than the expected value, the control function of the L6920 directs the energy stored in the inductor to be transferred to the load. This is accomplished by alternating ...
