摘要： Various techniques directed to providing temporary peak power from a switching regulator are disclosed. In one aspect, a switching regulator includes a switch that is to be coupled between a power supply input and an energy transfer element of the power supply. A controller is coupled to be responsive to a feedback signal to be received from an output of the power supply. The controller is coupled to switch the switch in response to the feedback signal to regulate the output of the power supply. An oscillator is coupled to provide an oscillating signal to the controller to determine a maximum switching frequency of the switch. The oscillating signal is coupled to oscillate at a first frequency under a first moderate load condition at the power supply output. The oscillating signal is coupled to oscillate at a second frequency under a second peak load condition at the power supply output.

摘要： An example power supply controller includes a regulation circuit, a current sense circuit, and a response circuit. The regulation circuit is coupled to regulate a sense terminal to a voltage level. The current sense circuit is coupled to the sense terminal to sense a current through the sense terminal a measurement delay period after a magnitude of the current through the sense terminal reaches a first threshold current level. The response circuit is coupled to the sense circuit and is responsive to the current through the sense terminal only after the measurement delay period.

摘要： A method, in a power supply controller, of responding to an increase in current through a terminal of the power supply controller, is disclosed. The method includes regulating the terminal to a first voltage level and sensing a magnitude of a first current through the terminal while the controller is regulating the terminal to the first voltage level. The method also includes providing an initial response by the power supply controller in response to the magnitude of the first current exceeding a first threshold current level and then regulating the terminal to a second voltage level after the magnitude of the first current exceeds the first threshold current level. The magnitude of a second current through the terminal is sensed while the controller is regulating the terminal to the second voltage level and the controller determines a final response based on the magnitude of the second current.

摘要： A power supply controller measuring impedance includes a sense circuit coupled to a sense terminal. A regulation circuit is coupled to the sense circuit and is also coupled to regulate the sense terminal to a first voltage level when a current flowing through the sense terminal is less than a first threshold current level. The regulation circuit is further coupled to regulate the sense terminal to a second voltage level when the current flowing through the sense terminal reaches the first threshold current level. A response circuit is coupled to the sense circuit and is responsive to the current flowing through the sense terminal when the sense terminal is regulated at the second voltage level.

摘要： An apparatus and method are disclosed to provide transformerless safety isolation in a power supply. One example regulated power converter includes input terminals included in a primary circuit of the power converter. Output terminals are included in a secondary circuit of the power converter. A plurality of safety capacitors including first and second safety capacitors are also included. Each of the plurality of safety capacitors includes a respective first terminal coupled to the primary circuit and a respective second terminal coupled to the secondary circuit. The plurality of safety capacitors galvanically isolates the primary circuit from the secondary circuit. A power switch is included in the primary circuit. The power switch is coupled such that switching of the power switch causes energy to transfer between the primary and secondary circuits through the plurality of safety capacitors. Substantially all of the energy that is transferred between the primary and secondary circuits is through the plurality of safety capacitors.
