Intersil's New Power Module Solves the 5 Most Difficult Power Supply Challenges

ISL8200M in Space-Saving Surface Mount QFN Package Simplifies Design, Lowers Design Risk and Speeds Time-to-Market

MILPITAS, CA--(Marketwire - January 25, 2010) - Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog and mixed-signal semiconductors, today announced the ISL8200M, a compact, scalable power module. This flexible new module provides designers an easy-to-use general-purpose power solution that satisfies a wide range of point-of-load (POL) power requirements.

The ISL8200M is a 10A, highly integrated POL regulator in a surface mount QFN package that includes a PWM controller, power MOSFETs, power inductor and associated discrete components. It is ideally suited for a broad range of applications in the computing, telecommunications and networking infrastructure, and industrial markets.

Today, power system designers face considerable challenges, and performance demands continue to increase. Unless an engineer is an expert at power supply design, "getting it right the first time" is very unlikely. Thanks to its robust, highly-integrated construction, the ISL8200M makes designing a high-performance POL regulator nearly foolproof.

Five Compelling Features and Benefits

     1.  Simple and easy to use:  Constructing a high-performance POL
         regulator with the ISL8200M is fast and simple.  All you need are
         input and output capacitors, a few support components, and a
         single resistor to program the output voltage.
     2.  Lowers risk:  Power system performance requirements continue to
         rise, increasing the risk of design problems. The ISL8200M
         delivers state-of-the-art performance without the risk. And
         with fewer components, reliability in the field is improved as
     3.  Faster time-to-market:  Power system design often happens late in
         the product development cycle. The ISL8200M minimizes the risk of
         product delays-simply drop it on the board, and it works. Now it's
         easy to get the power supply right the first time, and get your
         product to market on schedule.
     4.  Smaller footprint saves space:  The ISL8200M's compact 15mm x 15mm
         package consumes very little PCB area.  And with its thin 2.2mm
         profile, the ISL8200M can be mounted on the back side of the PCB
         where space is typically free.
     5.  Simplifies inventory:  Today, designers must use different power
         solutions depending on the output current demands. The ISL8200M
         enables a single solution covering < 10 amps to 60 amps. This
         simplifies inventory by allowing a single part to satisfy a wide
         range of POL regulator applications.

Patented Current-Sharing Architecture

The ISL8200M accepts input voltages from 3V to 20V, and supports output voltages from 0.6V to 6V. A patented current-sharing architecture allows up to six modules to be paralleled for a total output current of 60A. Remote voltage sensing also assures precise regulation even in low voltage, high current applications.

Programmable and synchronizable switching frequency allows designers to optimize efficiency and control switching noise in noise-sensitive systems. An enable pin and power-good indicator can be used to sequence modules to meet FPGA and processor power sequencing requirements.

Unlike some competing power modules, the ISL8200M is assembled in a thermally enhanced surface mount QFN package with leads around the perimeter. This provides for more reliable soldering, solder quality inspection and easy access with oscilloscope probes.

Pricing and Availability

The ISL8200MIRZ is available now in a 23-lead QFN package, with prices starting at $15.86 each in 1,000-piece quantities.
