Fairchild Semiconductor Delivers the Smallest Footprint Complementary MOSFET Device to Break the 1 Amp Continuous Current Barrier

Integrated Solution Offers Superior Thermal and Efficiency Benefits in Low-Voltage and Battery-Powered DC/DC Converter Applications

SAN JOSE, Calif.—(BUSINESS WIRE)—Dec. 14, 2004— Fairchild Semiconductor (NYSE: FCS) introduces the smallest footprint complementary MOSFET solution capable of delivering greater than 1 Amp continuous current in miniature "spot" power and point of load (POL) DC/DC switching converter designs. The FDC6020C integrates two MOSFETs into one ultra-small SuperSOT(TM)-6 FLMP (Flip-chip in a Leaded Molded Package); traditional solutions must use either two devices or a larger footprint package to offer similar high-performance specifications.

Products that benefit from the FDC6020C's excellent thermal and efficiency characteristics include set-top boxes, digital still cameras and hard disk drives. The FDC6020C's low threshold gate (VGS = 2.5 V) simplifies designs using 3.3 V bus converters or single cell Li-Ion batteries. It does this by eliminating the need for charge pump circuits when higher gate drive voltages are not available. Additionally, each of the device's MOSFETs provide excellent RDS(on) characteristics (52 milliohms for the P-Channel and 27 milliohms for the N-Channel, at 4.5 V). The FDC6020C's junction-to-case thermal resistance (1 degree C/W) and junction-to-ambient thermal resistance (68 degrees C/W) facilitate the highest possible current densities while maintaining optimum operating temperatures.

The FDC6020C is housed in a SuperSOT-6 FLMP. The footprint of the FLMP is only 9mm2 with a maximum height profile of 0.8mm. This advanced packaging eliminates conventional wire-bonds. This provides a low electrical resistance and still maintains the critical mechanical tolerances necessary to enable the backside of the die and the backside of the package to be coplanar. Coplanar construction also provides a low thermal resistance path between the PCB and MOSFET die (drain connection).

"Many ultra-portable products are powered by a rechargeable single cell Li-ion battery, rechargeable NiMH batteries, and alkaline cells. All of these power sources feature a continuously declining output voltage as the batteries are discharged during use. Consequently, the output voltage of these ICs, including the output drive voltages which control the MOSFETs in the circuit, will decrease as well," said Mike Speed, Fairchild's communications marketing manager. "Fairchild's FDC6020C -- with its ability to fully function at low input voltages, its thermal enhancements and its compact packaging -- meets these electrical requirements and greatly alleviates the space concerns confronting ultra-portable designers."

This lead-free (Pb-free) product meets or exceeds the requirements of the joint IPC/JEDEC standard J-STD-020B and is compliant with the European Union requirements, which will take effect in 2005.

The FDC6020C expands Fairchild's solutions for DC/DC conversion, which include Microcouplers(TM), optically isolated error amplifiers (FOD27XX), fast recovery diodes and PWM controllers.
