Abstract:
A DC:DC converter having an input node coupleable to a source of operating Vin potential, and at least a Vo1 output node, the converter comprising:a transformer including a first primary winding, a second primary winding, and at least a first secondary winding;means for selectively switching said Vin potential across said first primary winding and across said second primary winding such that time periods are permitted having a characteristic selected from a group consisting of (a) time periods during which neither primary winding is coupled to said Vin potential, and (b) overlapping time periods during which both primary windings are coupled to said Vin potential;an inductor coupled in series between a source of said Vin and a first node of said first primary winding and a first node of said second primary winding; andmeans for rectifying switched potential appearing across said secondary winding to provide said Vo1 at said output port.
