摘要： A control circuit operable to control the switching of switching elements in a switched mode power supply. The control circuit comprises a switching control signal generator operable to generate control signals for switching the switching elements such that the switched mode power supply converts an input voltage (Vin) to an output voltage Vout). The control circuit further comprises an operation mode setting module which is operable to receive a signal (I) indicative of a current flowing to a load that is connected to an output of the switched mode power supply, and operable to cause the switching control signal generator to generate the control signals so as to operate the switched mode power supply in a continuous conduction mode or a pulse skipping mode in dependence upon the current.

摘要： A control circuit for a switched mode power supply (SMPS) has an input voltage reference voltage generator arranged to receive a signal indicative of an input voltage of the SMPS and is arranged to generate a reference signal directly proportional to the input voltage. An error signal generator of the control circuit is arranged to receive a signal indicative of an output voltage of the SMPS and arranged to generate an error signal based on the reference signal generated by the input reference voltage generator and based on the output voltage of the SMPS. A duty cycle control signal generator of the control circuit is arranged to generate a control signal, to control the duty cycle of the SMPS, in dependence upon the error signal.

摘要： A switched mode power supply includes a switching device, the switched mode power supply being operable to convert an input voltage (Vin) to an output voltage (Vout) by switching the switching device, and a voltage regulator operable to generate a feedback signal based on at least one of the output voltage and an output current of the switched mode power supply. The power supply further comprises an overload detector, which is arranged to receive the feedback signal and operable to determine whether the feedback signal is outside a predetermined range. If the feedback signal is outside the predetermined range, the overload detector is operable to determine that the switched mode power supply is in an overload state, and when an overload state is determined, perform control to place the switched mode power supply in a non-operational state.

摘要： A power supply and method for reliable turn-on of a switched mode power supply (SMPS) in which the same transformer is used for providing power from the primary side to both the main output of the SMPS and a secondary side voltage regulator a train of voltage pulses are transmitted, from the primary side to the secondary side. The voltage regulator generates a feedback signal indicating when it has turned on and is operating, and the transmission of pulses within the train is controlled based on the detection of feedback signal. In this way, only the required amount of power to switch on the voltage regulator is transferred to the secondary side during a start-up operation and excess power at the main output is prevented, thereby avoiding distortion of the desired start-up ramp figure.
