Abstract
A small form factor power supply includes a switching transformer, control circuitry and rectifier circuitry, each contained within a housing. The switching transformer has a planar core and windings which surround at least a portion of the planar core. The control circuitry includes at least one surface mounted component, to control a switching device to couple a source of DC power to a primary of the switching transformer at a switching frequency. The rectifier circuitry is coupled to a secondary of the switching transformer to provide a DC voltage. The housing contains the switching transformer, the control circuitry and the rectifier circuitry, wherein a height of the housing is not greater than 0.75 inches.
