Abstract: A transformer driver circuit couples to a transformer having a primary winding, a secondary winding, and a transformer tap that is connected to a first voltage source. The primary winding electrically connects at its ends to respective unipolar controllable current sinks that form part of an integrated circuit. The transformer driver circuit operates by each current sink selectively sinking current from the end of the primary winding to which it is connected so as to cause current to flow in the secondary winding in a push-pull fashion. The transformer driver circuit further includes a load electrically connected to the secondary winding and protection circuitry operative to protect the integrated circuit from input levels greater than it can withstand.

Abstract: Disclosed is a transformer driver circuit, which in one aspect comprises a transformer comprising a primary winding and a secondary winding and a transformer tap, the latter electrically connected to a first voltage source. The primary winding is electrically connected at both ends to respective unipolar controllable current sinks that form part of an integrated circuit. The circuit operates by each current sink selectively sinking current from the end of the primary winding to which it is connected so as to cause current to flow in the secondary winding in a push-pull fashion. The circuit further comprises a load electrically connected to the secondary winding; and protection circuitry operative to protect the integrated circuit from input levels greater than it can handle. In another aspect there is a similar transformer drive circuitry which may or may not be partly on an integrated circuit and have protection circuitry.
