    Abstract: An overshoot suppression circuit comprises a switch for coupling to an output of a voltage regulation module and a voltage detector for detecting an output voltage at the output. When the load to the voltage regulation module changes from heavy to light to result in the output voltage higher than a threshold, the voltage detector turns on the switch to release energy from the output, and thereby the output voltage is suppressed to produce overshoot to damage the load coupled to the output.

    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.
