Integrated Power Management for Embedded Processors and Subsystems with Multiple Power Rails

Embedded and application processors and other components in complex systems require multiple power rails and multiple power domains. Using discrete devices for power management in these types of systems can be costly. Power Management Integrated Circuits (PMICs), which integrate multiple voltage regulators and control circuits into a single chip, are excellent options for implementing complete power supply solutions. They reduce component count and board space while easily and cost effectively managing system power. 

PMICs are an excellent fit for embedded processing in a wide range of applications such as Internet of Things (IoT), edge computing, medical and Industrial IoT, Electric Vehicles (EVs) and autonomous vehicles. We also offer System on Modules (SOMs) that combine a PMIC with an industrial-grade microprocessor (MPU), along with other devices, to simplify your development and speed up your time to market.

Advantages of Designing With PMICs

  • Simplifies power management in complex embedded systems
  • Provides power supplies for processing systems
  • Optimizes power consumption and extends battery life
  • Helps control complex power systems
  • Reduces circuit board space
  • Reduces time to market and risk
  • Reduces engineering and sourcing effort
