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.
