Coreless Transformer technology is basis for gate drivers

The 1EDI EiceDRIVER from Infineon is a single channel gate driver for applications with isolation voltages of up to 1200V. The galvanically isolated driver components are based on the Coreless Transformer Technology which enables output currents of up to 6A on separate output pins, says Infineon.

The basic system includes UVLO (under voltage lockout) for IGBTs and MOFETs as well as an active shutdown in the event that the driver is not connected to the power supply. The MOSFET driver is optimised for use with Superjunction (CoolMOS) technology.

IGBT-only variants with 4, 2 and 0.5A are also due to be released.

The drivers are supplied in a compact DSO-8 housing and can be used at temperatures up to 125°C, for example in industrial drives, inverters, welding equipment, induction cooking appliances and power supplies for servers or telecommunications.
