16 High-Resolution PWM with Fine Edge Placement

This section describes the features and use of the High-Resolution Pulse-Width Modulation (PWM).

This flexible module provides features to support many types of Motor Control (MC) and Power Control (PC) applications, including:

  • AC-to-DC Converters
  • DC-to-DC Converters
  • AC and DC Motor Control: Brushed DC, BLDC, PMSM, ACIM, SRM, Stepper, etc.
  • Inverters
  • Battery Chargers
  • Digital Lighting
  • Power Factor Correction (PFC)
  • Eight Independent PWM Generators, each with Dual Outputs and Fine Edge Placement
    • Resolution down to 78 ps
  • Four Auxiliary Independent Generators, each with Dual Outputs
  • Operating Modes:
    • Independent Edge PWM mode
    • Variable Phase PWM mode
    • Independent Edge PWM mode, Dual Output
    • Center-Aligned PWM mode
    • Double Update Center-Aligned PWM mode
