Switches meet 1W initiative
Three new power switches address 100-250W range switch mode power supplies (SMPS) for applications such as colour televisions, DVD receivers.
Leveraging its pre-eminence in power, Fairchild Semiconductor has released three new green FPS products that address 100-250W range switch mode power supplies (SMPS) for applications such as colour televisions, DVD receivers, audio devices, and plasma display panels With the introduction of the new FSCQ series, Fairchild now offers a complete green FPS portfolio addressing 1 to 250W applications

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.
The Green FPS products are highly integrated offline power switches that incorporate a fully avalanche-rated SenseFET and current mode PWM IC in a single package to reduce system standby power, EMI emissions, total component count and board space.
These products feature burst mode operation for standby mode (under 0.1W at 265V AC) to satisfy the International Energy Agency's (IEA) 1W Initiative aimed at reducing standby power losses to below 1W.
This standard dictates the amount of standby energy a system's SMPS can consume during standby operation.
"Fairchild continues to respond to trends and design challenges in the growing market for 'green' solutions".
"These new green FPS products provide a unique combination of excellent operating performance and low standby power in highly integrated packaging?, said SangTae Im, Fairchild's Power Supply Product Manager.
"Our FSCQ series products offer system designers solutions for optimising power and performance in high-power applications such as DVD receivers and colour TVs?.
The 100W-rated FSCQ0765RT, 170W-rated FSCQ1265RT and the 200W-rated FSCQ1565RT are specifically designed for quasiresonant offline SMPSs.
The quasiresonant convertor lowers EMI, making these green FPS devices well suited for applications that are sensitive to noise, and allows higher power conversion efficiency compared with conventional hard-switched convertors with a fixed switching frequency.
Fairchild's green FPS products feature overcurrent protection for high reliability in abnormal conditions, as well as built-in soft-start that protects the SMPS during startup.
The FSCQ series products are available in a TO-220F-5L package.
The packages are lead-free (Pb-free) and meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020B and are compliant with the European Union requirements, which will take effect in 2005.
