    Abstract: A transistor switching regulator having a pulse width control which includes a minimum pulse output, a ''''ramp-up'''' start pulse output and a feedback controlled running pulse output sequenced to start up and run the transistor switching regulator in a controlled manner. The three pulse outputs are derived from an emitter coupled astable multivibrator having a linearizing boot strap circuit, coupled to one of its emitter output circuits and having a long time constant for gradually charging the capacitor of the boot strap circuit during the ramp-up operation. A circuit which is sensitive to the boot strap circuit during the charging of its capacitor provides a sequence of pulses of gradually increasing width during the ramp-up operation.

    Abstract: A heat-conductive honeycomb ceramic spacer (11) having an array of apertures therein for facilitating assembly of a semiconductor device including a plurality of semiconductor stacks (13) using a low-profile contact comprising a foil (12) with raised portions corresponding to the locations of apertures in the ceramic spacer for forming contacts with the semiconductor stacks when the spacer and the stacks are sandwiched between the foil and another conductive sheet (14). Use of such a foil also allows disconnection of defective stacks in the device which includes extra stacks to compensate therefore, according to an n - x philosophy. Solder preforms may be included on the stacks and enhanced connections made to the foil of conductive sheet by causing reflux of the solder preforms. The invention may also be applied to multi-layer device constructions.
