Akros Energy$ense™ – Technology Overview

akros-tech-overview

Akros Energy$ense™ technology is a collection of energy management features that are essential for simple and cost-effective implementation of real-time and adaptive energy management designs. Given the competitive and regulatory nature of the industry, it's no longer sufficient to just have a subset of such features to check mark the Green-compliance box. Instead, a Total Energy Management paradigm is essential and Akros' Energy$ense™ technology enables OEMs and system designers to address Energy Consumption and Management issues in a comprehensive manner.

Energy$ense™ Technology

  • Real Time Energy Monitoring:
    – Input Power measurements, per converter
    – Power system health monitoring and alarms
  • High Efficiency Converters:
    – Including Light load management (94% peak efficiency)
    – Industry leading Ultra-low standby and sleep mode power (<10uA) to design for various eu compliance standards
  • Digital Power Control:
    – Built-in digital dimming control for backlight applications
    – Independent rail-margining, converters enable/disable for adaptive power profiles
  • Fast Transient Response:
    – Rapid shut-down/full-load wake-up of system processors for most energy savings
  • EMI Energy Management:
    – Multi-channel synchronization
    – Spread-spectrum clocking to reduce radiation & filtering

Platform Benefits for OEMs

OEMs face the continuous challenge of adding increasingly more distinct functionality in electronic equipment while reducing power consumption, development time and costs. Energy$ense™ products provide multiple benefits, that not only make implementation of Total Energy Management architectures practical, but very cost effective also.

Low-Energy Consumption Designs: Energy$ense™ products are built on foundation of Synchronous High-Efficiency Converters (94% peak) that are optimized for use across light-load to full-load ratings. Unlike most multi-rail PMUs, these converters have fully independent control (like ccm/dcm control, startups, shutdowns, margining, etc.) to enable each rail independent behavior based on system specific requirements.

Simplified Designs for EU Energy Compliance Standards: Given most equipment spend most of the time in sleep/standby operating modes, it's equally important to minimize energy draw in those modes. Energy$ense™ products are designed with very low Standby and Sleep mode power is kept low (<10uA) to enable design for latest EU Energy Compliance standards like eup Lot3/6/7 requirements, Code of Conduct (CoC) requirements.

Simplified Platform Power Design Optimization: With the capability of Energy$ense™ solutions to provide extensive Hardware (HW, pin programmed) features, and, additional Software (SW, I²C) based features the platform designer can optimize the features needed per power design while staying with the same DC-DC device family. Roadmaps of power designs starting with HW features and extending to SW based designs are simplified because the DC-DC power designs will be very similar and often the same.

Dynamic Power Management Implementations: Various power design modes lend themselves for a dynamic and adaptive implementation of power profiles. Given reality of very high leakage current in modern sub-micron geometries, best way to conserve power is by turning on/off or scaling the supplies as needed in the system. Examples include RF Power Amplifier supply management in Time-Domain Multiplexed communication applications like LTE, disabling device clusters/ASICs where certain functionality is not needed, or linearly scaling the supply based on processor performance need. Energy$ense™ products have built-in hardware and software control to enable such features.

Remote Monitoring & Control: With ability to measure real-time power consumption, as well as availability of wide range of alarms through software, like Over Temperature, Over Voltage, Power Goods, etc. it's now possible for the OEMs to monitor the device remotely, diagnose issues ahead of time and manage and control them as necessary down to power-domain level.

Faster Time to Market: Advanced programmability of devices leads to faster development cycles and product EMC qualification, thereby reducing development resources and time. Energy$ense™ technology enables advanced system clock management features that simplifies the design for EMC compliance. The reduction in number of IC count simplifies the development, validation and qualification phases.

Cost Effective Designs via Energy$ense™ Family Reuse: By providing a pin compatible family of devices with flexible DC-DC controller and converter design options, Akros Energy$ense based solutions allow the OEM to re-use DC-DC design concepts across multiple system platforms. This increases the volume of many BOM components by leveraging multiple platform volume scale, thereby reducing total BOM cost structures.
