Fairchild Semiconductor has launched the industry’s first Power Factor Correction (PFC) Smart Power Module (SPM) to implement the Partial Power Factor Correction Switching Converter (PSC) circuit topology, which is applicable for 1-3kW air conditioners. 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, 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 PFC-SPM’s application benefits include: Very low thermal resistance—(Rqjc(IGBT) = 2.8°C/W for IGBT, Rqjc(DIODE) = 2.6°C/W for diode) with the aid of DBC substrate; Low acoustic noise due to an optimized gate-driving IC; Isolation voltage rating of 2500 VRMS and Increased system reliability provided by the gate-driving IC’s under-voltage and over-current protection.
In addition to the PFC-SPM, Fairchild’s portfolio of power modules covers full range of consumer appliance applications from 50W to 3kW. 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-free Mini-DIP package.
The PFC-SPM is available now at a price of US$13.48 each (100 pcs) with delivery time of 12 weeks ARO.
