摘要： A per-phase quick response generation circuit generates a quick response signal to determine a quick response pulse to be inserted into a pulse width modulation signal of the corresponding phase. The quick response pulse will force the upper power switch of the corresponding phase on to increase the current supply ability during load transition. A multi-phase voltage regulator with the quick response generation circuit can have different quick response pulse widths for the interleaved phases, so as to decrease the current imbalance period of the voltage regulator after load transition.

摘要： A method and apparatus are provided for a switching mode converter to improve the light load efficiency thereof. The converter is thus operated with three modes by monitoring a feedback signal and a supply voltage. When the feedback signal indicates that loading gets light enough, the converter is switched from the first mode to the second mode, and during the second mode some cycles are skipped. If loading is too light, the converter is switched from the second mode to the third mode, and during the third mode more cycles will be skipped.

摘要： A single-chip common-drain JFET device comprises a Drain, two gates and two source arranged such that two common-drain JFETs are formed therewith. Due to the two JFETs merged within a single chip, no wire bonding connection is needed therebetween, thereby without parasitic inductance and resistance caused by bonding wire, and therefore improving the performance and reducing the package cost. The single-chip common-drain JFET device may be applied in buck converter, boost converter, inverting converter, switch, and two-step DC-to-DC converter to improve their performance and efficiency. Alternative single-chip common-drain JFET devices are also provided for current sense or proportional current generation.

摘要： An electrostatic loudspeaker driver includes a class-D amplifier and a demodulator circuit. The class-D amplifier is operated with a PWM signal, creating an amplified digital signal according to an input signal. A low-pass filter in the demodulator circuit filters out the PWM carrier frequency in the digital signal and retrieves an audio signal therefrom. The efficiency is improved significantly and heat sink is no longer needed.
