Preliminary Data Sheet
AC non-switchable regulators
The IXYS IXC series of high voltage
current regulators consists of non-
switchable, 2-terminal, AC and DC
current regulators.
TO-220 AB
(IXCP)
This family consists of two DC current
regulators connected internally in
series to regulate the current to a
specified value in both directions. Its
output characteristics in quadrants 1
and 3 are the same as shown in Figure
1 so that the current regulation is also
the same in both directions. Parts are
only available in the TO-220 package.

Applications
This is a family of extremely stable,
high voltage current regulators with
the typical output characteristic shown
in Figure 1. The temperature stability
is based on a threshold compensation
technique and uses IXYS' most
recently developed high voltage
process. The complete family will be
capable of providing other
intermediate current levels which can
be programmed on-chip during the
manufacturing phase.

IXC Series
Application Examples
DC and AC Overvoltage
Suppression
The regulator can be used as a
voltage surge suppressor. The device
is again connected in series with the
lead (Fig. 5) and would normally
operate at a current level lower than
the plateau (Fig. 6a). Any incoming
voltage surge (Fig. 6b) less than the
breakdown voltage of the regulator will
be clamped by the IXCP regulator to
voltage less than the plateau current
times the effective resistance of the
load.
Fig. 5. DC surge suppression
source of a highly stable current to
produce a usable voltage reference
(Fig. 7). This would be effectively
independent of temperature and a low
cost approach. A high voltage
reference is also possible, thanks to
their high breakdown voltages.
Fig.8. Low cost current regulators
instead of fuses
The obvious advantages to having this
regulator as fuse substitute are:
z Prevents a "dip" in the power
supply during a fault condition
z Regulator remains intact
z Can be easily tied in with logic to
indicate a "down state" board
R = 100 Ω Vout = 3.5 V nominal
R = 50 Ω
R = 25 Ω
Vout = 1.75 V nominal
Vout = 0.875 V nominal

high stability
Fig. 6a. DC surge suppression
Instantaneous "Fuse"
Another application would be
protection against sudden voltage
droops on voltage supply lines to logic
cards in computing systems, resulting
from one component suddenly
shorting to ground. Normal fusing
networks will draw considerable
current during the time it takes for the
fuse to clear. This could cause a
sufficient dip in power rail voltage to
cause malfunctions of the other logic
cards, even with fast-blow fuses (Fig.
8). The current regulator in series with
the logic card restricts the current to
its own operating level (Fig. 9).
Therefore the voltage supply does not
become overloaded and the regulator
remains intact.

across load

series with each board
Soft Start-Up Circuits
Here the regulator characteristic will
clamp initial current surges which can
occur when power is initially applied
to a load. The device, with its 450 V
capability could, for example, be used
with a DC power supply or with AC
mains to limit the initial high inrush of
current into lamp filaments, thereby
increasing the filament life several
times. It could, therefore, be used
effectively in lighting displays and in
the transportation lighting industries.
Testing & Handling
Recommendations
z For initial assessment of the parts
where the customer may test the
device characteristics in free air
without heat sinking, the continuous
power dissipation should be kept
within 1.5 W at ambient of 25°C.
(R
= 80 K/W for TO-220, and
RthtJhAJA= 100 K/W for TO-252)
The current regulator thus provides an
"instantaneous fusing" function. When
the logic component is replaced, the
regulator resumes its normal
functioning mode.
z Normal electrostatic handling
precautions for MOS devices
should be adhered to.
Highly Stable Voltage Sources
Another obvious application would be
to use the current regulator as a
