ABSTRACT:
A switching circuit uses multiple common-drain JFETs to serve as the low-side switches of the switching circuit, and each of the low-side JFET is coupled between a high-side switch and a power node. Since a JFET can endure high voltage at both drain side and source side, and has good heat dissipation capability at drain side, the drain of the low-side JFET is coupled to the power node to enhance the heat dissipation capability and accordingly, all the low-side JFETs are allowed to be packaged in a same package to reduce the PCB layout area.
