Fairchild Semiconductor Introduces Smart Power Module For Partial Power Factor Correction Switching Converters

South Portland, ME -- Fairchild Semiconductor introduces the Power Factor Correction Smart Power Module to implement the Partial Power Factor Correction Switching Converter circuit topology. By triggering the IGBTs at every half cycle of the line current, the PFC-SPM FSAB20PH60 provides 97% of power factor and full compliance with the mandatory PFC standard IEC61000-3-2.

Compared to alternative "discrete" solutions, Fairchild's PFC-SPM enables simpler designs by combining four rectifier diodes, two IGBTs, a gate-driving IC and a thermistor in a single, thermally efficient module. The device's compact (44 mm x 26.8 mm) Direct Bonded Copper (DBC) substrate package is identical in size and configuration to Fairchild's motor control (Motion-SPM) module. The two modules are designed to be mounted side-by-side to share a single heat sink.

"The partial switching method is very popular in 1-3 kW air conditioners, however utilizing discrete components--the only currently viable alternative to the new PFC-SPM--requires more assembly time and the required additional heat sink complicates and encumbers the design process," said Taehoon Kim, vice president of Fairchild's High Power product line. "Combining our new PFC-SPM with our Motion-SPM provides our customers with a highly cost-effective solution for improving design productivity and ultimately, the dependability of their products."
