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： Techniques are disclosed to detect a fault in the feedback circuit of a switching power supply while the power supply operates in a mode where the output is below its regulated value. The power supply delivers maximum power at a given switching frequency without a feedback signal while the output is below its regulated value. A fault protection circuit substantially reduces the average output power if there is no feedback signal for the duration of a fault time. When there is no feedback signal, the power supply increases the maximum output power by increasing the switching frequency before the end of the fault time to increase the output to a regulated value. The presence of a feedback signal when the output reaches a regulated value restores the original switching frequency and returns the output to its unregulated value. The absence of a feedback signal at the end of the fault time engages the fault protection circuit to substantially reduce the output power.

摘要： A reduced cost voltage regulation circuit for switched mode power supplies. In one example, a current sense circuit includes a current sense terminal of a voltage regulation circuit. A voltage difference between the current sense terminal and a voltage reference terminal of the voltage regulation circuit is substantially fixed when a first current to be sensed by the current sense circuit at the current sense terminal is substantially equal to a first current sense threshold. A power transistor is also included and is coupled to the current sense circuit and coupled between a power supply input terminal of the voltage regulation circuit and a power supply output terminal of the voltage regulation circuit. The power transistor is coupled to be switched in response to the first current to be sensed by the current sense circuit at the current sense terminal to control a transfer of energy from the input of the power supply to the output of the power supply to regulate an output voltage of the power supply.

摘要： An example controller for use in a power converter includes an oscillator and a logic circuit. The oscillator is to be coupled to a switch of the power converter and determines a switching cycle period of the switch. The logic circuit is also to be coupled to the switch to control a duty cycle of the switch in response to a magnitude of a feedback signal to regulate an output of the power converter. The logic circuit controls the duty cycle of the switch such that a control loop gain of the power converter is substantially constant during a transition of the controller between duty cycle control modes.
