IDT’s Patented Solution Offers Intelligent, Scalable, Distributed Output Current Capability to Meet the Cross-platform Power Requirements of Various Applications with a Single PMIC
SAN JOSE, Calif. — (BUSINESS WIRE) — June 24, 2013 — 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.
