Gate driver reference design for SemiSouth normally off SiC JFETs enables very fast turn-on/ turn-off
SemiSouth Laboratories, Inc., the leading manufacturer of silicon carbide (SiC) products for high-power, high-efficiency, harsh-environment power management and conversion applications, today announced a reference design and applications note which describes a gate driver optimized for high speed, hard switching of the company’s normally-off SiC vertical JFETs. The design enables very fast turn-on and turn-off in Isolated Bridge topologies and provides a peak output current of +6/- 3A for fast turn-on transients yielding record low switching energy losses.
SuitComments Dan Schwob, SemiSouth’s VP of Sales & Marketing: “The applications note and demo board describe a driver circuit which enables designers to take advantage of the benefits of our high performance, highly efficient and small JFETs, while keeping the BOM low.” Applications include hard-switched bridge topologies, inverters/converters and IT/telecoms power supplies.
