- Raspberry Pi selects MxL7704 Five
Output Universal PMIC to power their new single-board computer, the
Raspberry Pi 3 Model B+
MaxLinear, Inc. (NYSE:MXL), a leading provider of radio
frequency (RF), analog and mixed-signal integrated circuits for the
connected home, wired and wireless infrastructure, and industrial
and multimarket applications, today announced that Raspberry Pi has
selected MaxLinear’s MxL7704 Universal PMIC to power its latest
single-board computer, the Raspberry Pi 3 Model B+.
The MxL7704 enables the Raspberry Pi 3 Model B+ to be more
compact and flexible. The PMIC’s I2C interface communicates with
the computer’s on-board SoC for dynamic voltage scaling, status
monitoring, sequencing control and PGOOD routing. These unique
features provide the Raspberry Pi 3 Model B+ with more knowledge
and control of power status and performance than previous systems
using discrete power management solutions.
In addition to added power management flexibility and
functionality, the MxL7704 also decreases the space and number of
components required to power the computer’s SoC and surrounding
ICs. A typical 4-channel analog power solution can utilize nearly
150 components. More components can be accommodated if soft-start,
margining, or sequencing functionalities are implemented
discretely. The MxL7704 supplies four power rails and a 100mA LDO,
uses less than 80 components and includes many features not
available in a basic analog solution. The IC is available in a
compact, 5mm x 5mm QFN package.
The MxL7704 includes four synchronous step-down buck regulators
that provide system, memory, I/O and core power from 1.5A to 4A. An
on-board 100mA LDO provides clean 1.5V to 3.6V power for analog
sub-systems. This PMIC utilizes a conditional sequencing state
machine that is flexible enough to meet the requirements of
virtually any processor.
"We worked closely with Raspberry Pi all the way from product
definition to product release,” said Tuomas Hollman, MaxLinear
Senior Director of Marketing, Power Management Products. "This very
open collaboration resulted in the MxL7704, which provides 5 rails
pre-optimized for ease of use in single-board computer systems,
with a host of features that allow monitoring, telemetry and
additional flexibility."
"Working closely with MaxLinear on the MxL7704 design has been
great. Despite the challenging requirements and schedule, our close
collaboration has been both a lot of fun and has resulted in a
device that meets or exceeds our original engineering and
commercial goals," said James Adams, Chief Operating Officer,
Raspberry Pi. "The MxL7704 has allowed us to improve both the
output currents and efficiency of the power rails on the new
Raspberry Pi 3 Model B+ as well as reduce the overall cost of the
power-chain by removing the need for external sequencing and
monitoring components (as compared to the Raspberry Pi 3 Model
B)."
About Raspberry Pi
The Raspberry Pi Foundation is a UK-based charity that works to
put the power of digital making into the hands of people all over
the world, so they are capable of understanding and shaping our
increasingly digital world, able to solve the problems that matter
to them, and equipped for the jobs of the future.
We provide low-cost, high-performance computers that people use
to learn, solve problems and have fun. We provide outreach and
education to help more people access computing and digital making.
We develop free resources to help people learn about computing and
how to make things with computers, and train educators who can
guide other people to learn.

the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as
amended. Forward-looking statements include, among others,
statements concerning the MxL7704 and statements concerning or
implying the performance of MaxLinear’s technologies, their
potential use cases, and the potential impact of these technologies
on our business and future operating results. These forward-looking
statements involve known and unknown risks, uncertainties, and
other factors that may cause actual results to be materially
different from any future results expressed or implied by the
forward-looking statements. Forward-looking statements are based on
management’s current, preliminary expectations. In particular, our
future operating results are substantially dependent on our
assumptions about market trends and conditions and our expectations
with respect to recently completed acquisitions, including our
ability to integrate our recently completed acquisition of Exar
Corporation. Additional risks and uncertainties arising from our
operations generally and our recently completed acquisitions
include intense competition in our industry; our dependence on a
limited number of customers for a substantial portion of our
revenues; uncertainties concerning how end user markets for our
products will develop; potential uncertainties arising from
continued consolidation among cable television and satellite
operators in our target markets and continued consolidation among
competitors within the semiconductor industry generally; our
ability to develop and introduce new and enhanced products on a
timely basis and achieve market acceptance of those products,
particularly as we seek to expand outside of our historic markets;
potential decreases in average selling prices for our products;
risks relating to intellectual property protection and the
prevalence of intellectual property litigation in our industry;
indemnification obligations of Exar arising from a recent
divestiture; the impact on our financial condition of acquisition
indebtedness and cash usage arising from the Exar transaction; our
reliance on a limited number of third party manufacturers; and our
lack of long-term supply contracts and dependence on limited
sources of supply. In addition to these risks and uncertainties,
investors should review the risks and uncertainties contained in
our filings with the Securities and Exchange Commission (SEC),
including the information under the caption “Risk Factors” in our
