摘要： A controller includes a switching control coupled to switch a power switch of a power converter to regulate an output of the power converter. A sensor is coupled to receive a signal from a single terminal of the controller. The signal from the single terminal is representative of a line input voltage of the power converter during at least a portion of an on time of the power switch, and an output voltage of the power converter during at least a portion of an off time of the power switch. The switching control is responsive to an output of the sensor, and includes a first current source, an internal voltage supply coupled to the first current source, and a buffer circuit coupled to receive the signal from the single terminal. The first current source is coupled to supply a first current to the buffer circuit.

摘要： A power converter controller includes an input sense circuit to receive an input sense signal representative of an input of a power converter. A zero-crossing detector is coupled to the input sense circuit to be responsive to the input sense signal falling below a first zero-crossing threshold and rising above a second zero-crossing threshold to determine zero-crossing intervals. A timer circuit is coupled to the zero-crossing detector to determine peak intervals and to synchronize an enable signal generated to enable the input sense circuit to sense the input of the power converter during the peak intervals of the input of the power converter. A comparator circuit is coupled to the input sense circuit and the timer circuit to detect if the input of the power converter is greater or less than one or more thresholds during the peak intervals of the input of the power converter.

摘要： A circuit includes a control circuit coupled to detect whether an electrical energy source is coupled to an input of a power converter. A switch is coupled to the control circuit to transfer energy from the input of the power converter to an output of the power converter during a first operating mode. The control circuit is coupled to drive the switch in the first operating mode when the electrical energy source is coupled to the input of the power converter. The control circuit is coupled to drive the switch in a second operating mode when the electrical energy source is uncoupled from the input of the power converter. The control circuit is coupled to discharge a capacitance coupled between input terminals of the power converter through the switch to a threshold voltage in less than a maximum period of time in the second operating mode.

摘要： A power converter includes a dc input having first and second terminals. A main converter is coupled to the first terminal of the dc input. A standby circuit coupled to the second terminal of the dc input and the main converter. The main converter is coupled to control a transfer of energy from the dc input through the standby circuit to a main output of the main converter during a normal operating condition of the power supply. The standby circuit is coupled to decouple the main converter from the second terminal of the dc input during a standby operating condition of the power converter. A standby converter is coupled to the first and second terminals of the dc input to control a transfer of energy from the dc input to a standby output of the standby converter during the standby operating condition of the power converter.
