Overview

Our integrated circuits and reference designs for air conditioner outdoor unit systems help you maximize energy efficiency and minimize acoustics for your design while considering cost.

Design requirements

    Modern air conditioner outdoor unit designs require:

  • High-efficient power factor correction (PFC) with optimized bill of material (BOM) and size.
  • Efficient and dependable compressor control with low acoustic noise.
  • Highly-dependable valve control.
  • Robust and reliable communication.
  • Accurate environmental sensing.
