Abstract: An ultra-high voltage device has a high voltage path established from a high voltage N-well through a first metal layer to a second metal layer, and a contact plug electrically connected between the high voltage N-well and the first metal layer. The contact plug has a distributed structure on a horizontal layout to improve the uniformity of the ultra-high voltage device such that the current in the high voltage path will be more uniform distributed so as to avoid the localized heat concentration caused by non-uniform current distribution that would damage the ultra-high voltage device. Multiple fuse apparatus are preferably connected to the first metal layer individually. Each the fuse apparatus includes a poly fuse to be burnt down when an over-load current flows therethrough.

Abstract: A class-D audio amplifier is protected by thermal regulation which decreases the gain of the class-D audio amplifier by asserting an over-temperature signal when the temperature of the class-D audio amplifier is detected to be higher than a threshold. The output of the class-D audio amplifier is therefore reduced by the smaller gain, and the chance for the class-D audio amplifier to stop working due to overheating is greatly reduced.

The ramp generator determines the slope turning points for the multi-slope ramp signal according to the error signal of the PWM power converter and thereby improve the transient response of the PWM power converter. Preferably, the slope turning point of the multi-slope ramp signal varies with the average of the error signal and is thus adaptive to the error signal and thereby the load condition.

Abstract: A switching regulator includes a low-side switch having a body diode. During the low-side switch is on, a zero-current sense circuit monitors the inductor current of the switching regulator and triggers a signal to turn off the low-side switch when the inductor current falls down to a zero-current threshold, to prevent reverse inductor current from the output terminal of the switching regulator. A body-diode turn-on time controller monitors the turn-on time of the body diode and adjusts the zero-current threshold according thereto, and the turn-on time of the body diode can be reduced to an optimal interval subsequently. The self-adjustable zero-current threshold is adaptive according to the application conditions, such as the inductor size, input voltage and output voltage of the switching regulator.

Abstract: 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.
