摘要： There are disclosed herein various implementations of composite III-nitride semiconductor devices having turn-on prevention control. In one exemplary implementation, a normally OFF composite semiconductor device comprises a normally ON III-nitride power transistor and a low voltage (LV) device cascoded with the normally ON III-nitride power transistor to form the normally OFF composite semiconductor device. The LV device is configured to have a noise-resistant threshold voltage to provide the turn-on prevention control for the normally OFF composite semiconductor device by preventing noise current from flowing through a channel of the normally ON III-nitride power transistor in a noisy system.

摘要： Some exemplary embodiments of a III-nitride switching device with an emulated diode have been disclosed. One exemplary embodiment comprises a GaN switching device fabricated on a substrate comprising a high threshold GaN transistor coupled across a low threshold GaN transistor, wherein a gate and a source of the low threshold GaN transistor are shorted with an interconnect metal to function as a parallel diode in a reverse mode. The high threshold GaN transistor is configured to provide noise immunity for the GaN switching device when in a forward mode. The high threshold GaN transistor and the low threshold GaN transistor are typically fabricated on the same substrate, and with significantly different thresholds. As a result, the superior switching characteristics of III-nitride devices may be leveraged while retaining the functionality and the monolithic structure of the inherent body diode in traditional silicon FETs.

摘要： One exemplary disclosed embodiment comprises a two-terminal stacked-die package including a diode, such as a silicon diode, stacked atop a III-nitride transistor, such that a cathode of the diode resides on and is electrically coupled to a source of the III-nitride transistor. A first terminal of the package is coupled to a drain of the III-nitride transistor, and a second terminal of the package is coupled to an anode of the diode.

摘要： A synchronous buck converter having an improved transient response during output current stepdown. The device includes series and shunt MOSFETS, a first driver circuit to turn the series MOSFET on and off according to a variable duty cycle determined by an error signal representing the difference between the voltage output of the converter and a reference voltage, a sensing circuit operative to provide a control signal output when the duty cycle for the series MOSFET is zero; and a second drive circuit responsive to the control signal output of the sensing circuit to turn off the shunt MOSFET. The sensing circuit operates by detecting when the error signal is of a lower amplitude than the minimum value of the ramp waveform used to generate the duty cycle for the series MOSFET.
