AMG-PP130
FACT SHEET
Universal DSP-based PFC solution for applications
requiring power factor values close to unity
The AMG-PP130 is a universal DSP-based PFC solution to be used in applications requiring
power factor values close to unity. Typical applications are high power DC motors and lighting
systems. The controller is based on boost topology and is fully software controlled. The PFC
algorithm is loaded into the DSP from an on-chip, non-volatile memory after Reset. The
parameters of the algorithm can be changed using a two-wire interface (I2C compatible).
