IDT Announces Innovative Power Management Solution Validated for Intel® AtomTM Processor-based Applications

Business Wire
Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI), the
Analog and Digital Company™ delivering essential mixed-signal
semiconductor solutions, today announced that it has developed and
validated an intelligent, scalable, and distributed power
management solution for Intel® Atom™ processors, Intel® Xeon®
processors and Intel® Core™ processors. IDT’s innovative power
management solution is designed to meet the cross-platform power
requirements of various Intel-based applications with a single
power management IC (PMIC). IDT’s patented solution has been
system-level validated to support these processor families.
The IDTP9145 is a scalable, programmable, multi-channel PMIC
specifically designed to support the power management requirements
of Intel Atom processor-based SoCs. Unlike traditional solutions
that require a different PMIC for different power requirements, the
highly-versatile IDTP9145 leverages IDT’s intelligent, scalable,
distributed power sources (IDTP9147), enabling system designers to
add phases and output current to the internal DC/DC regulator as
needed by the application. This feature minimizes development risk
and offers tremendous flexibility for point-of-load regulation,
circuit board routing, and thermal distribution.
“We are excited to announce the development and validation of
our patented power management solution for Intel® processor-based
platforms,” said Arman Naghavi, vice president and general manager
of the Analog and Power Division at IDT. “The IDTP9145 PMIC offers
industry-first design features, giving customers a means to
configure, re-configure, and scale their power management solution
to support evolving power requirements across multiple product
platforms. The highly versatile solution services a wide-range of
market segments, spanning from micro-servers and embedded markets,
to consumer electronics, including tablets and netbooks.”
“Solutions like IDT’s help deliver an innovative and
comprehensive power solution with the versatility to support Intel®
processor-based platforms in a wide range of applications, such as
print imaging, digital signage and medical devices,” said Ken
Caviasca, general manager with Intel’s (NASDAQ: INTC) Intelligent
Systems Group. “In addition, IDT’s solution has undergone
system-level validation and demonstrated its ability to support
varying processor power requirements with a single PMIC.”
The IDTP9145 PMIC is a complete power management solution that
includes: five step-down DC/DC regulators (20 A total peak
current), seven LDOs, a 10-bit ADC, multiple GPIOs, and a
high-speed I2C interface. IDT’s patent-pending architecture offers
seamless transitions between modes of operation to ensure
high-efficiency for different power loads. In addition, the
solution provides a high degree of configurability through
one-time-programmable (OTP) memory that can be programmed prior to
shipment. This enables customers to set custom default power
sequences and configurations without the high-speed I2C
interface.
The IDTP9147 companion distributed power sources are controlled
by the IDTP9145 PMIC, allowing designers to command up to eight
external devices as though they were integrated into the main PMIC
itself. Each optional device provides up to 6 A of additional peak
current, for a total of 48 A of scalability in addition to the
IDTP9145's 20 A of integrated capability. The distributed
nature of the devices distributes heat across the board and greatly
simplifies PCB routing and stack-up requirements near the PMIC – an
area that is often a challenge to design. In addition, the
transient voltages and currents of the additional phases are
contained to the power sources’ immediate areas, helping to avoid
inductive interference and minimize EMI.
Differing from Driver-MOSFET (DrMOS) solutions, IDT’s solution
leverages a proprietary two-wire interface with no sensitive analog
feedback traces or individual pulse width modulation (PWM) line
connections, thus minimizing the number of PCB traces and avoiding
potential signal coupling issues. In addition, automatic signal
integrity calibration practically eliminates trace length and
proximity concerns, allowing customers to separate the power
sources and host PMIC as needed to optimize the system.
