2.2 Design Considerations

The reference design has the following sub-blocks:

  • 85-265VAC input and EMI filter
  • High performance single stage PFC using UCC28810, provides 24VDC for motor control
  • High integrated MOSFET and algorithm sensorless BLDC controller using MCF8315/MCF8316 for motor control
  • Cost-optimized MCU MSPM0L/MSPM0C device for MCF8315/ MCF8316 control and support IR Sensor control.
