EV6R11 KIT

Figure 6: Boosting the IX6R11 outputs for larger MOSFETs.

With the addition of High Current MOSFET Drivers on the outputs, the IX6R11's typical 6A peak output current

capability can be "boosted" to drive the latest IXYS MOSFETS & IGBTs. Figure 6 shows the addition of two

IXDD414's. These are CMOS high-speed MOSFET drivers that have a 14A Peak Output Drive Capability, allowing

the IX6R11 to drive a pair of IXFK90N20Q 90A/200V Power MOSFETs. The 2 Ohm gate resistors shown should

be Non-Inductive High Performance Film resistors such at those available from Caddock. Particular attention also

needs to be paid to Suppy By-passing, Grounding, and minimizing the Output Lead Inductance when designing such

a high power circuit layout.
