Description

The Power JFET transistor from Lovoltech is a device that presents a Low Rdson allowing for improved efficiencies in DC-DC switching applications. The device is designed with a low threshold such that drivers can operate at 5V, which reduces the driver power dissipation and increases the overall efficiency. Lower threshold produces faster turn-on/turn-off, which minimizes the required dead time. The transistor “No Body Diode” provides a very low associated parasitic capacitance Cds. A Schottky Diode is added for applications where a freewheeling diode is required. Ringing is also reduced so that a lower voltage

device may be a better solution.
