Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI), the
Analog and Digital Company™ delivering essential mixed-signal
semiconductor solutions, today announced the industry’s first
intelligent, scalable, distributed power management solution for
portable multi-core application processors. IDT’s patented
technology offers flexibility to add incremental output current
without modifying the controller power management IC (PMIC). This
allows the solution to scale with varying system-on-chip (SoC)
power requirements and helps to overcome PCB routing and thermal
challenges.
IDT’s innovative technology is a power management solution
consisting of a main PMIC with communication lines for the
connection and control of IDT’s compact, external, add-on power
sources, for increased power output capability. Unlike traditional
solutions that require different PMICs for different applications,
IDT’s scalable solution minimizes development time and risk with a
single PMIC that can be re-used and re-optimized to support the
evolving power requirements of various processor platforms. In
addition, the distributed nature of the add-on power sources offers
tremendous advantages for point-of-load regulation, circuit board
routing, and thermal distribution. IDT’s innovative approach is an
ideal solution for advanced portable devices, such as tablet PCs,
clam shell devices, smartphones, ebooks, high-end digital cameras,
client solid-state drives (SSD), and set-top boxes. The IDTP9165
PMIC and IDTP9167 companion power source are IDT’s first devices to
offer this technology.
“IDT’s scalable approach to power management brings a new level
of performance and flexibility to the fast-paced market of consumer
portable electronics,” said Arman Naghavi, vice president and
general manager of the Analog and Power Division at IDT. “When our
customers design a new platform of portable devices, it’s difficult
to predict exactly how much output power will be needed to optimize
each system. As a result, PMICs are typically overdesigned, making
the systems costly, inefficient, and physically larger. By
providing our customers a flexible power management platform to
mirror the needs of their processor platform, they can now focus
their attention on a single PMIC, and simply scale the output power
to optimize each system. In addition, this modular approach offers
invaluable thermal benefits by allowing the designer to spread the
power dissipation across the board – a serious challenge in today’s
ultra-compact portable devices.”
The IDTP9165 includes five integrated synchronous step-down
DC/DC regulators, 11 LDOs, a real time clock (RTC), a 10-bit ADC,
multiple GPIOs, and a high-speed I2C interface. The IDTP9167 add-on
power sources are controlled by the IDTP9165 PMIC, allowing the
designer to command up to eight external devices as though they
were integrated into the main PMIC itself. Each optional device
efficiently provides up to 6 A of additional peak current,
distributing heat across the board and greatly simplifying PCB
routing and stack-up requirements near the PMIC – an area that is
often a challenge to design. In addition, the transient currents
and voltages of the additional phases are contained to the external
power sources’ immediate areas, helping to minimize EMI and avoid
inductive interference.
An innovative control system leverages a proprietary two-wire
interface without sensitive analog feedback traces or individual
pulse width modulation (PWM) line connections. This minimizes the
number of PCB traces and avoids potential signal coupling issues,
allowing the customer to easily scale the number of add-on power
sources required for each application. Furthermore, automatic
signal integrity calibration practically eliminates proximity and
trace length concerns, allowing customers to separate the host PMIC
and power sources as needed to optimize the system.
