Intelligent Power

AC to DC | DC to DC | DC to AC | Wireless Charger and Receiver | Solar | Battery Management | Digital Power

Traditional power supply designs use analog ICs with fixed functionality to provide regulated power. An intelligent power supply integrates a microcontroller (MCU) or Digital Signal Controller (DSC) to deliver a fully programmable and flexible solution for a variety of applications.

Examples of Intelligent Power Supply Functions:

  • Full digital control of power control loops
  • Power supply sequencing and hot-swap control
  • Programmable soft-start profiles
  • Output voltage margining
  • Current foldback control
  • Load sharing and balancing
  • Compensation network control and adjustment
  • Regulation reference adjustments
  • AC RMS voltage measurement
  • Power factor correction
  • Power supply history logging and fault management
  • Communications

Scalable Solutions for Power Conversion Applications

An intelligent power supply does not need to be complex or expensive. We deliver everything you need to create your power conversion design: low-risk product development, lower total system cost, faster time to market, outstanding technical support and dependable delivery and quality. Offering MCUs and DSCs ranging from 6 to 144 pins, we have a suitable device for every application. Many simple tasks can be implemented with a low-cost MCU that contains basic peripherals. For more demanding applications, many of our MCUs and DSCs have innovative on-chip peripherals that are designed specifically for power conversion. These peripherals include fast Pulse-Width Modulation (PWM) modules with special operating modes and high-speed Analog-to-Digital Converters (ADCs) for fast acquisition of power supply feedback signals. We also offer other complementary devices to support your design’s requirements. Use the links in the table below to learn more about our solutions.
