- Raspberry Pi has selected the MxL7704 Five-Output Universal
Power Management IC to power their new single-board computer, the
Raspberry Pi 4
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 the MxL7704 Universal PMIC to power its latest
single-board computer, the Raspberry Pi 4.

The MxL7704 complete power delivery system already powers the
popular Raspberry Pi 3 Model B+. The versatility of this universal
PMIC allowed it to be easily re-programmed to accommodate the new
current limit, sequencing and power requirements of the upgraded
SoC and surrounding ICs on-board the new Raspberry Pi 4.
The highly integrated MxL7704 provides all key power rails
required by the Raspberry Pi 4, including the low noise voltage
rail used for audio circuitry. It also handles the unique power
sequencing requirements of each rail with ease due to its
convenient I2C programmability. The MxL7704’s I2C interface
communicates with the computer’s SoC for dynamic voltage scaling,
status monitoring, sequencing control and PGOOD routing. These
features enable the Raspberry Pi 4 to save power by dynamically
reducing the voltage to the SoC when the system is idle and
boosting it when the processor is running at maximum speed.
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. It also features an integrated 8-bit ADC with 2
external inputs and temperature sensor that provide die temperature
monitoring, telemetry and additional flexibility. The Raspberry Pi
4 utilizes the MxL7704’s on-board ADC to determine if there is a
high current delivery USB power supply. All these features are
packed into a small 5x5mm 32-pin QFN package, which helps the
Raspberry Pi retain its small form factor.
“The MxL7704 provides five rails pre-optimized for ease of use
in single-board computer systems,” said James Lougheed, Vice
President of Marketing for MaxLinear’s High Performance Analog
Products. “The PMIC includes a host of features that allow
monitoring, telemetry and additional flexibility. These unique
features provide the Raspberry Pi 4 with knowledge and control of
power status and efficiency to ensure peak performance during
various operating conditions.”
“After using the MxL7704 very successfully on the Raspberry Pi 3
Model B+, we were very pleased to select it again to power our next
generation Raspberry Pi 4 Model B computer,” said James Adams,
Chief Operating Officer for Raspberry Pi (Trading) Ltd. “The
combination of highly efficient, high current buck supplies in a
very cost-effective package which also included I2C control,
dynamic voltage scaling, programmable sequencing as well as a low
noise LDO and ADC has been key to making sure we have met our
design and cost targets for Raspberry Pi 4.”
