摘要： A communication system for use in a switching module includes a low-side control block coupled to control switching of a low-side switch of the switching module. The low-side control block is further coupled to be referenced with a low-side reference system ground. A high-side control block is coupled to control switching of a high-side switch of the switching module. The high-side control block is further coupled to be referenced with a floating node of the switching module. During steady state operation, the low-side control block is coupled to send signals during each switching cycle to the high-side control block to turn the high-side switch on and off. A status update is communicated from the high-side control block to the low-side control block through a first single-wire communication link.

摘要： A transient event detector includes a first reference generator, an adjustable low-pass filter, and a comparator. The first reference generator coupled to scale the input current signal to generate a first reference current signal that tracks the input current signal. The adjustable low-pass filter circuit is coupled to receive the input current signal and to generate a filtered input current signal such that a magnitude of a slope of the filtered input current signal is less than the magnitude of the slope of the input current signal during a transient event. The first comparator is coupled to generate an event detection signal that indicates the presence of the transient event in response to a value of the filtered input current signal reaching a value of the first reference current signal. The adjustable low-pass filter circuit is configured to increase the cutoff frequency in response to the event detection signal.

摘要： An example controller for a power converter includes a track and hold circuit, a sample and hold circuit, and drive logic. The track and hold circuit receives a signal that is representative of an output voltage of the power converter. The track and hold circuit includes a first capacitor that provides a first voltage that tracks the signal and then holds the first voltage. The sample and hold circuit then samples the first voltage that is held on the first capacitor. The sample and hold circuit includes a second capacitor that holds a second voltage representative of the first voltage after a fixed sample period. The second capacitor is larger than that of the first capacitor. The drive logic controlling the first switch to regulate the output of the power converter includes disabling the first switch during an on time of the first switch responsive to the second voltage.

摘要： A controller for use in a power converter includes a state selection circuit coupled to receive an input voltage sense signal representative of an input voltage, a switch current sense signal representative of a switch current of a power switch, and a feedback signal representative of an output quantity of the power converter. The state selection circuit is coupled to generate an input voltage signal in response to the input voltage sense signal, an input current signal in response to the switch current sense signal, and an input threshold signal in response to the feedback signal. A state machine circuit is coupled to the state selection circuit to generate a drive signal in response to the input voltage signal, the input current signal, and the input threshold signal to switch the power switch to control a transfer of energy from an input to an output of the power converter.

摘要： A power converter controller includes an oscillator, a drive circuit, and a frequency modulator. The drive circuit receives a clock signal from the oscillator and generates a drive signal in response thereto to control switching of a switch of the power converter. The frequency modulator controls the frequency of the clock signal in response to an inductor voltage across an inductor of the energy transfer element to reduce a peak-to-peak ripple value in an output current of the power converter. The frequency modulator controls the frequency of the clock signal during each line half cycle to be a fixed frequency when the inductor voltage is less than or equal to a threshold voltage. When the inductor voltage is greater than the threshold voltage the frequency modulator varies the frequency to be less than the fixed frequency to adjust a shape of an input current of the power converter.

摘要： A controller includes a multiplier block that is coupled to receive an input voltage signal, an input current signal, and an output voltage signal that are representative of a power conversion system. The multiplier block outputs a multiplier block output signal responsive to a product of the input voltage signal and the input current signal divided by the output voltage signal. A signal discriminator outputs a error signal responsive to the multiplier block output signal. The error signal is representative of a difference between a portion of the multiplier block output signal that is greater than a reference signal and a portion of the multiplier block output signal that is less than or equal to the reference signal. A switch controller generates a drive signal responsive to the error signal to control switching of a power switch to regulate an average output current of the power conversion system.
