摘要： A shunt regulator for use in a power converter having an energy transfer element for regulating a transfer energy of the output signal delivered to the load. An auxiliary winding of the energy transfer element being utilized to produce an internal bypass voltage, VBP, at a bypass pin coupled to an external capacitive load, the shunt regulator including a two-mode operational amplifier that produces an output signal that controls a shunt current through the shunt switch. At power-up, or at low load conditions, the operational amplifier operates in a low-power mode of operation with low quiescent current. When a current comparator circuit senses that the shunt current exceeds a predetermined level, the current comparator circuit sets a latch which produces a logical signal that causes the operational amplifier to switch to a high-power mode of operation.

摘要： A bleeder circuit emulator for use in a power converter to compensate and increase the current demand from the Triac dimmer above its holding current. The circuit includes an input voltage modifier and a leading edge dimming detection circuit. The input voltage modifier receives an input voltage signal that is representative of a magnitude of an input voltage of the power converter and selectively provides a modified input voltage signal to an input of a controller in response to receiving a control signal. The modified input voltage signal is representative of a value that is less than the magnitude of the input voltage. The leading edge dimming detection circuit generates the control signal to engage the input voltage modifier to generate the modified input voltage signal in response to detecting leading edge dimming at an input of the power converter.

摘要： An energy storage circuit for use with a power converter includes a base capacitor coupled between an input bus and a ground potential, and an adjust capacitor. A switching device is coupled in series with the adjust capacitor between the input bus and the ground potential. A voltage regulator coupled between a control terminal of the switching device and ground. The voltage regulator has an input coupled to the second internal node, wherein when the power switch is turned on a signal at the second internal node is representative of a fluctuating input voltage. The voltage regulator is activated when the fluctuating input voltage is in a crest region, thereby turning the switching device off and disengaging the adjust capacitor. The voltage regulator is deactivated when the fluctuating input voltage is in a valley region, thereby turning the switching device on and engaging the adjust capacitor.

摘要： A method of fabricating a multi-layer structure for a power transistor device includes performing, within a reaction chamber, a nitrogen plasma strike, resulting in the formation of a nitride layer directly on a nitride-based active semiconductor layer. A top surface of the nitride layer is then exposed to a second source. A subsequent nitrogen-oxygen plasma strike results in the formation of an oxy-nitride layer directly on the nitride layer. The nitride layer comprises a passivation layer and the oxy-nitride layer comprises a gate dielectric of the power transistor device.

摘要： A controller and a method for controlling a power converter includes a sample block coupled to generate a first, second, and third sample by sampling an input sense signal that is representative of an input voltage of the power converter. An enable signal is asserted when a first difference between the first sample and the second sample exceeds a first threshold. An edge signal is asserted when both the enable signal is asserted and a second difference between the first sample and the third sample exceeds a second threshold. A drive circuit is coupled to output a drive signal in response to the edge signal. The drive signal is for controlling a switch coupled to regulate an output of the power converter.
