FACT SHEET

DSP-based PFC for Power Factors close to Unity,

including Low Voltage DC Power Supply and MCU

The AMG-PS132 is a universal DSP-based PFC solution with switching-mode power supply to

be used in applications requiring power factor values close to unity and a highly efficient DC

power supply. Typical application areas for the AMG-PS132 are high power motors and light-

ing systems. The power factor controller (PFC) is based on boost topology and is fully soft-

ware controlled by the DSP. The device includes an AVR^®compatible MCU with peripherals.

The PFC algorithm is initially loaded from the MCU into the DSP. PFC parameters can also be

changed during run time. The IC contains an auxiliary switching-mode power supply in flyback

topology with current feedback. It is designed to supply external circuitry with a highly stable

low voltage.

Highlights

 Independent DSP based PFC regulation engine (values >0.99)

 8-bit AVR^®compatible MCU

 Secondary SMPS controller for auxiliary low voltage generation
