FPS-4N DC To 28MHz
Pulse Width Agile Gate Drive Module
The FPS-4N Gate Drive Module is designed for use
with DE-SERIES power MOSFETs. It was devel-
oped as a design tool to support the system de-
signer in the evaluation of and prototyping using the
DE-SERIES devices. It provides gate drive and
MOSFET mounting, thereby freeing the designer to
focus on the specifics of the system under develop-
ment.
By utilizing design techniques developed by DEI,
the FPS-4N can drive DE-150 and DE-275 Series
MOSFETs at frequencies to 28MHz with pulse width
agility from <15ns to continuous, and rise times of 3-
4ns. The FPS-4N can also drive the DE-375 at fre-
quencies to 18MHz, with comparable pulse width
and switching speeds.
Provisions for heat sinking the MOSFET and a strip-
line drain and source interconnect topology allow
the user to easily incorporate the FPS-4N driver and
power MOSFET as a pulse width agile module in
high speed, high power circuits such as class D and
class E RF generators, high speed pulsed voltage
sources and pulsed current sources.
The control gate input to the FPS4N is a TTL into
5
, high true logic signal. This drive is a voltage
source that is level shifted to +15V before being ap-
plied to the DE-SERIES gate. Therefore gate drive will
follow the input control gate in time, with a delay (TD)
as specified in the specifications section of this data
sheet.
The output section provides for drain and source con-
nections (SD1 and SD2) in a stripline topology.
Mounting holes are provided at the four corners so
that the PCB may be secured to a chassis, and there
are two holes on either side of the device for high
power mounting of the DE-Series device to a heat
sink. LEDs are used as support power indicators.
A detailed discussion of the design and topology of
the FPS-4N is addressed in the “Gate Driver Design
For Switch Mode Applications” technical note, avail-
able for download from DEI’s web site at http://www.
directedenergy.com. For users interested in designing
this circuit into their systems, the circuit board layout
and fabrication package is available from DEI. Con-
tact DEI for more information.
The FPS-4N is provided as a fully assembled and
tested module. The DE-Series MOSFET is sold sepa-
rately.
