Figure 1, DRF1203 Simplied Circuit Diagram
The Simplied DRF1203 Circuit Diagram is illustrated above. By including the driver high speed by-pass capacitor (C1), their contribution
to the internal parasitic loop inductance of the driver output is greatly reduced. This, coupled with the tight geometry of the hybrid, allows
optimal gate drive to the MOSFET. This low parasitic approach, coupled with the Schmitt trigger input (IN), Kelvin signal ground (SG) and the
Anti-Ring Function, provide improved stability and control in Kilowatt to Multi-Kilowatt, high Frequency applications. The IN pin is the input for
the control signal and is applied to a Schmitt Trigger. Both the FN and IN pins are referenced to the Kelvin ground (SG.) The signal is then ap-
plied to the intermediate drivers and level shifters; this section contains proprietary circuitry designed specically for the ring abatement. The
power drivers provide high current to the gate of the MOSFETS.
