Abstract: A multi-mode switching regulator is capable of operating in a buck mode of operation, a boost mode of operation, and a buck-boost mode of operation. In the buck-boost mode of operation, the output voltage is regulated by adjusting a number of switch state transitions from a first state to a second state relative to a number of switch state transitions from the first state to a third state, and the duty cycle of each of the states is fixed from cycle to cycle in which the particular state occurs.

Abstract: A transformer. According to one embodiment, the planar transformer has a first winding, a first conducting surface adjacent to the first winding, a second winding and a second conducting surface adjacent to the second winding. The first conducting surface is coupled to a first ground and the second conducting surface is coupled to a second ground.
