摘要： An example controller for a switched mode power supply includes a zero-crossing detector and a drive signal generator. The zero-crossing detector is coupled to generate a zero-crossing signal representative of a phase angle of a dimmer output voltage for a half line cycle of the power supply. The drive signal generator controls switching of a switch to regulate an output of the power supply in response to a feedback signal representative of the output. The drive signal generator further controls switching of the switch to adjust dimming of the output of the power supply in response to the phase angle indicated by the zero-crossing signal.

摘要： An example controller for a switched mode power supply includes a zero-crossing detector, drive logic, and an on-time extension block. The zero-crossing detector is coupled to generate a first signal prior to a zero-crossing of an input voltage of the power supply. The drive logic is to generate a drive logic output signal in response to a feedback signal, where the drive logic output signal is representative of an initial on-time. The on-time extension block is coupled to the zero-crossing detector and to the drive logic to generate a drive signal in response to the drive logic output signal. The drive signal controls switching of a switch to remove charge from a filter capacitor of the power supply. The drive signal is representative of a total on-time of the switch equal to a sum of the initial on-time and an extended on-time, where the extended on-time is responsive to the first signal.

摘要： A method of operation for flyback power converter includes operating a controller of the flyback power converter in a regulation mode when a control signal is below a first threshold. The control signal is provided as an input to a terminal of the flyback power converter. When the control signal is below a second threshold and above the first threshold, the controller is operated in a limiting mode. The controller is operated in an external command mode when the control signal is below a third threshold and above the second threshold. Lastly, when the control signal is above the third threshold, the controller is operated in a protection mode.

摘要： An example controller for a switched mode power supply includes a drive signal generator and a zero-crossing detector. The drive signal generator is to be coupled to control switching of a switch included in the power supply to regulate an output of the power supply. The zero-crossing detector is coupled to the drive signal generator and coupled to receive a current sense signal representative of a switch current flowing through the switch. The zero-crossing detector generates a zero-crossing signal in response to comparing the current sense signal with a reference signal representative of a zero-crossing current threshold. The zero-crossing signal indicates when a zero-crossing condition of an ac line input voltage of the power supply exists.
