Modules offer compact green route to PFC
Three new Smart Power Modules are designed for full-switching power factor correction in motor drive applications in the 3-6kW power range.
Fairchild Semiconductor has released three new Smart Power Modules (SPM) designed for full-switching power factor correction (PFC) in motor drive applications in the 3-6kW power range Each PFC-SPM device integrates two fast-recovery diodes, two freewheeling diodes, two IGBTs, a gate-driver IC, a shunt resistor and a thermistor into one thermally efficient 44 x 26.8mm package

Dual-output buffer for DDR SDRAM modules
Fairchild Semiconductor has introduced a dual-output registered buffer for 184-pin, 2.5V PC200/PC266, 72bit-wide registered double data rate (DDR) SDRAM modules.
Bus hold makes logic more predictable
Fairchild Semiconductor has made a number of additions to its LCX family, the logic industry standard for 3.3V applications.
As highly integrated modules, PFC-SPM devices save 50% board space compared with discrete solutions, and increase reliability with built-in protection features.
These devices also provide 99% power factor (typical) to meet the mandatory PFC standard (IEC61000-3-2) and 40kHz switching operation to mitigate power loss.
Fairchild's PFC-SPM devices offer designers a compact "green" solution ideal for air conditioners and industrial inverter designs by increasing system reliability and efficiency while reducing board space.

Two low voltage PLL clock drivers designed for use in high-speed memory clocking applications are now available from Fairchild Semiconductor.
"Fairchild's new PFC-SPM devices expand our SPM portfolio to address PFC in 3-6kW consumer and industrial applications", said Taehoon Kim, Vice President of Fairchild's Functional Power Group.
"These modules optimise thermal efficiency by utilising Fairchild's Direct Bonded Copper (DBC)-based transfer-moulded packaging technology".
"They also incorporate existing SMPS IGBT and Stealth diode technology to significantly reduce power losses".
"Our new line of PFC-SPM products demonstrate how Fairchild applies proven design, manufacturing and packaging expertise to specifically address our customers' design requirements in a broad range of applications".
These PFC-SPM devices enhance reliability in end systems by integrating a thermistor for temperature monitoring and a shunt resistor for current sensing.
The built-in resistor also reduces part count by eliminating the need for the external bulky components required by discrete solutions.
Further reliability features include undervoltage (UV) and overcurrent (OC) protection provided by their integrated gate-driving IC.
They also provide an isolation voltage rating of 2500V RMS for 1min and their packaging complies with basic creepage and clearance spacing for UL certification No E209204.
The FPDB20PH60 (600V/20A), FPDB30PH60 (600V/30A) and the FPDB50PH60 (600V/50A) are available in lead (Pb)-free Mini-DIP packages.
These products meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with the European Union requirements now in effect.
