Abstract:
A Mosgated device for driving a TV deflection coil, comprising:an IGBT and power MOSFET having outputs coupled together in parallel with a base and gate node of said IGBT and MOSFET, respectively, being coupled together, such that said device has at least three nodes; said IGBT and MOSFET having respective effective die areas totalling less than an entire device die area; said MOSFET effective die area being from 10% to 100% that of said IGBT; said coupled IGBT and MOSFET permitting said device to have a linear characteristic of a power MOSFET at low forward current and low forward voltage; and said coupled IGBT and MOSFET permitting said device to have a low forward voltage drop at high current characteristic of an IGBT.
