Renesas Electronics recently launched its ISL91301B PMIC (Power Management Integrated Circuit), which has been designed into the latest Google Coral products. 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.
The Google Coral technology also paves the way for highly developed neural network processing for lower-power devices. The core of Coral is constituted by Google Edge Tensor Processing Unit (TPU) coprocessor. TPU coprocessor can easily perform about four trillion operations per second (TOPS) using just 0.5 watts energy per TOPS.
“We are thrilled to be collaborating with Google on their innovative, next-generation products,” said Andrew Cowell, VP of Renesas’ Mobility Infrastructure & IoT Power Business Division. “Our multi-phase PMIC employs Renesas’ industry-leading R5 modulation technology for a blazingly fast transient response, which allows Google’s designers to dynamically scale power to improve overall system performance.”
Renesas’ ISL91301B PMIC promises much higher efficiency and a smaller footprint power solution for users. It is ideally suited for all kinds of low-power, advanced AI processors. Renesas has equipped the ISL91301B with quad buck regulator outputs and, each one, can yield up to 4A at peak efficiency of 94 percent.
ISL91301 leverages the R5 Modulation Technology by Renesas. It helps it in faster-switching frequency, tuned compensation, and quick single-cycle transient response. The overall size of this solution stands at 70mm2. This simplifies the task for designers working on AI solutions as small as 2mm x 2mm x 1mm passive components, small capacitors, and low profile inductors.
If working on a battery-powered or a low-power AI product, it’s possible to rely on the ISL91301B PMIC’s high DC accuracy, faster dynamics, smaller capacitor size, and lower profile inductors.
“Renesas’ Multiphase PMICs provide our engineering team with the high-performance and design flexibility required to build Coral,” said Google hardware manager, Kai Yick. “Our collaboration with Renesas ensures our Edge TPU achieve the highest power efficiency to perform calculations offline and locally.”
