摘要： A switching mode power supply (SMPS) includes a transformer having a primary winding, a secondary winding for providing an output voltage, and an auxiliary winding. The SMPS also includes a power switch coupled to the primary winding. A first control circuit is coupled to the secondary winding, and is configured to provide a first electrical signal to the secondary winding when the output voltage of the SMPS is less than a reference voltage during a discontinuous time, whereupon a second electrical signal is induced in the auxiliary winding. A second control circuit is coupled to the auxiliary winding and the power switch. The second control circuit is configured to regulate the output of the SMPS by controlling the power switch in response to a feedback voltage signal from the auxiliary winding, and is further configured to turn on the power switch in response to the second electrical signal.

摘要： A key assembly for use in an electronic device is provided. The key assembly includes a plurality of dome switches and a plurality of single-piece keycaps. Each keycap identifies a row of keyboard characters. Each keycap has a plurality of character-representing portions separated by deforming portions. Each character-representing portion is associated with a separate one of the plurality of dome switches. The key assembly further comprises a plurality of actuators for activating the dome switches. Each actuator has a first side which is engaged by one of the character representing portions of the keycap. Each actuator has a second side which engages the dome switch associated with that character-representing portion.
