ABSTRACT OF THE DISCLOSURE A low voltage switching power supply designed to be compact and efficient for use with very high speed integrated circuits (VHSIC) has an innovative output transformer. Designed for use at greater than 50KHZ (nominally 100KHZ) the transformer is box-like in shape of high permeability ferrite material having one to four rectangular channels containing the primary and secon- dary winding. The secondary is electroplated copper with very low resistance while the primary is copper tape of some sixteen nominal turns. The power capability is 500 Watts with the output at 5 Volts DC or less and has an efficiency of greater than 98 percent. Up to three transformers can be paralleled to give a total output power of 1500 Watts.
