Renesas Electronics’ High-Efficiency Power Management IC Adopted in Google Coral AI Products

Sponsored by Businesswire

Renesas Electronics Corporation (TSE:6723), a premier supplier of
advanced semiconductor solutions, today announced its ISL91301B Power
Management IC (PMIC) is designed into the latest Google Coral
. They include the Mini PCIe Accelerator, M.2 Accelerator
A+E Key, M.2 Accelerator B+M Key, and System-on-Module (SoM). Google
Coral integrates seamlessly into processes at any scale, helping
designers create a variety of local artificial intelligence (AI)
solutions for several industries.

Google Coral technology enables advanced neural network processing for
low-power devices. At the heart of Coral is the Google Edge Tensor
Processing Unit (TPU) coprocessor, which is capable of performing four
trillion operations per second (TOPS), using 0.5 watts for each TOPS (2
TOPS per watt). For example, it can execute advanced mobile vision
models, such as MobileNet v2 at 400 FPS, in a power efficient manner.

The Renesas ISL91301B
PMIC offers a high efficiency and small footprint power solution that is
ideal for cutting-edge, low power edge AI processors. The ISL91301B has
quad buck regulator outputs, each delivering up to 4A (total 16A) with
94 percent peak efficiency. The PMIC leverages Renesas’ R5 Modulation
Technology for quick single-cycle transient response, tuned
compensation, and fast switching frequency. These features and a 70mm2
solution size make it easier for power supply designers to design a
small AI solution with 2mm x 2mm x 1mm low profile inductors, small
capacitors, and a few passive components. The ISL91301B’s low quiescent
current, superior light load efficiency, high DC accuracy and fast
dynamics is well suited for low-power or battery-powered AI products.

“We are thrilled to be collaborating with Google on their innovative,
next generation products,” said Andrew Cowell, Vice President, Mobility
Infrastructure & IoT Power Business Division at Renesas. “Our multiphase
PMIC employs Renesas’ industry-leading R5 modulation technology for
blazingly fast transient response, which allows Google’s designers to
dynamically scale power to improve overall system performance.”

Kai Yick, Google Hardware Manager said, “Renesas’ Multiphase PMICs
provide our engineering team with the high performance and design
flexibility required to build Coral. Our collaboration with Renesas
ensures our Edge TPU achieve the highest power efficiency to perform
calculations offline and locally.”
