Release of New Voltage Boost Converter Announced by IXYS

IXYS Corporation (NASDAQ: SYXI) disclosed today that its
Micronix division has released the MX846, a 50 mA regulated output
efficient voltage doubler designed for localized voltage step-up
applications. The MX846 provides a high efficiency regulated output
voltage with a minimum number of external components. Output
regulation is accurate to +/- 5% and is adjustable from 3 to 5V via
external resistors. Utilizing a charge pump topology eliminates the
need for an inductor, making the MX846 an optimum choice for low noise
applications.
   The MX846 uses a 1 MHz switching frequency, enabling the use of
smaller filter capacitors to meet the requirements of size sensitive
applications. With an operating range of 3 to 5 V and a typical
shutdown current of 1 microA, the MX846 is ideal for portable battery
devices. The MX846 has an operating temperature range of -40 degrees C
to +85 degrees C, and is available in a standard 8-lead, RoHS
compliant, SOIC package in tubes or on tape and reel.
   "We designed the MX846 to serve those applications where only low
voltage supplies are available, but the need for higher voltages is
required. The MX846 is a perfect choice for low voltage microprocessor
or lithium battery applications as it provides a regulated 3 to 5 volt
output suitable for higher complexity analog or mixed signal
functions," stated Bob DeCaro, Vice President and General Manager of
Clare Micronix.
   "With the strategic focus on power management ICs that complement
our line up of power semiconductors, our IC designers at Micronix have
shown their creativity in providing such solutions in silicon. It has
been demonstrated also in the recent introduction of the MX868 our 12
bit magnetic flux sensing IC, for digital power control applications,"
commented Dr. Nathan Zommer CEO of IXYS.
   Micronix, a leader in the design of high-performance analog and
mixed-signal integrated circuits, has produced over 450 application
specific integrated circuits (ASICs) and application specific standard
products (ASSPs) for the display, communications, consumer, and
medical markets. Micronix is a subsidiary company of IXYS Corporation,
a leading supplier of higher power semiconductors and modules for the
global power market. IXYS develops and markets primarily high
performance power and RF semiconductors and control ICs that are used
in controlling and converting electrical power efficiently in power
systems for telecommunication infrastructure, motor drives, medical
systems and transportation. IXYS also serves emerging markets with
digital and analog ICs that control flat panel displays, medical
instruments and telecommunication products. Additional information
