Fairchild Semiconductor Introduces Industry's First Smart Power Module (SPM(TM)) for Partial Power Factor Correction Switching Converters

Low switching loss circuit topology and advanced substrate packaging improve system reliability while speeding assembly time in 1-3 kW air conditioners South Portland, Maine--August 9, 2005--Fairchild Semiconductor (NYSE: FCS) introduces the industry's first Power Factor Correction (PFC) Smart Power Module (SPM(TM)) to implement the Partial Power Factor Correction Switching Converter (PSC) circuit topology, which is ideal for 1-3 kW air conditioners. By triggering the IGBTs at every half cycle of the line current, the PFC-SPM FSAB20PH60 provides 97% of power factor (typical) and full compliance with the mandatory PFC standard IEC61000-3-2, while offering better EMI (electromagnetic interference) characteristics than higher frequency switching topologies. 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--thus simplifying designs, speeding assembly and improving overall system reliability. "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." The PFC-SPM's application benefits include: o Very low thermal resistance (Rth(j-c)Q = 2.8 degrees C/W for IGBT; Rth(j-c)Q = 2.6 degrees C/W for diode) with the aid of DBC substrate; o Low acoustic noise due to an optimized gate-driving IC; o Isolation voltage rating of 2500 VRMS; and o Increased system reliability provided by the gate-driving IC's under-voltage and over-current protection. In addition to the PFC-SPM, Fairchild's comprehensive portfolio of power modules covers the full range of consumer appliance applications from 50 W to 3 kW. Offering both integrated and non-integrated solutions to meet the full range of OEM requirements, each specific solution exemplifies the company's proven design, manufacturing and packaging expertise. The PFC-SPM comes in a lead (Pb)-free Mini-DIP package.
