Abstract:
A power converter has a power transistor and inductor coupled in a conduction path with the power transistor. A switching frequency of the power transistor is reduced during a light load condition. A pulse width of a drive signal to the power transistor is controlled to select a current through the inductor and power transistor corresponding to the switching frequency to maintain a fixed output power of the power converter, and further to vary the current through the inductor and power transistor to maintain the fixed output power of the power converter over a range of switching frequencies. A first number of pulses of the drive signal to the power transistor during a first time period sets the fixed output power of the power converter. No pulses of the drive signal are provided during a second time period after the first time period.

Claim (Index 1):
A power converter, comprising:\n a power transistor; and a controller including an input coupled for receiving a signal representative of a current through a conduction path of the power transistor and an output coupled to a control input of the power transistor, wherein the controller establishes a relationship of the current through the power transistor given a primary inductance of a transformer of the power converter that provides fixed output power of the power converter and controls a drive signal to the control input of the power transistor to vary the current through the power transistor in accordance with the relationship to maintain the fixed output power of the power converter.
