MOSFETs keep their cool
Complementary 40V MOSFET uses dual DPAK packaging to increase system reliability, reduce board space and cut overall system cost.
New from Fairchild Semiconductor, the FDD8424H is a complementary 40V MOSFET that provides dual DPAK packaging and industry-leading thermal dissipation to increase system reliability, reduce board space and cut overall system cost Optimised for half- or full-bridge inverter designs, the FDD8424H is ideal for use in backlighting units (BLU) for LCD TVs, LCD monitors, motor drives and lamp drives

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.
Compared with alternative solutions, the FDD8424H in dual DPAK provides thermal resistance that is five and 10 times lower than solutions using 8-lead and dual SOIC (SO8) packages, respectively.
In addition, the integration of a P-channel high-side MOSFET and an N-channel low-side MOSFET into a single package allows a common drain connection within the device, simplifying board layout and reducing design time.
"Fairchild's FDD8424H offers display designers the ability to optimise the footprint and the thermal performance of their inverter designs", said Mike Speed, Fairchild's Marketing Manager for Communications and Consumer Products.
"The optimisation of on-resistance and gate charge in a dual DPAK offers improved switching performance compared with conventional SO8 solutions, resulting in lower heat dissipation and increased efficiency".
"Also, the FDD8424H provides 12% lower case temperature in backlighting inverters while driving eight CCFL lamps".
This lead (Pb)-free device meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020C and is compliant with European Union regulations now in effect.
