SAN JOSE, USA: Fairchild Semiconductor brings designers of servers, blade servers and routers the industry’s first sub-one mOhm 30V MOSFET in a Power 56 package.
This 30V MOSFET, the FDMS7650, functions as a load switch or an ORing FET. In server farms, these ORing FETs are used when many power supplies are arranged in parallel to share the load. Dissipating less power and delivering higher efficiency is critical for the overall efficiency of these server farms because the FETs are continually on.
The FDMS7650 is the first in Power56 packaging to break the 1mOhm barrier with a MAX RDS(ON) of only 0.99mOhm, reducing conduction losses and improving the overall efficiency of the application. This 30V MOSFET can deliver the same total RDS(ON) with half the number of FETs. As an example, in a typical application using 2.0mOhm MOSFETs, the solution would require twice the number of FETs.
The FDMS7650 is able to achieve this groundbreaking RDS(ON) through Fairchild's advanced-performance PowerTrench® MOSFET technology. This technology yields an exceptionally low RDS(ON), total gate charge (QG) and Miller Charge (QGD) – enhancements that result in high efficiency by minimizing conduction and switching losses.
This power MOSFET is one of Fairchild’s many MOSFETs that offer compelling advantages in power designs. Good examples are Fairchild’s 30V Dual N-Channel MOSFETs, the FDMC8200 and FDMS9600. The FDMC8200 typically features an RDS(ON) of 24mOhm on the high side and 9.5mOhm on the low side, enhancing efficiency in DC-DC applications.
The FDMS9600 offers synchronous Buck applications, an optimal power stage through low switching losses on the high side MOSFET and low conduction losses on the low side SyncFET MOSFET.

Fairchild launches new generation of super-junction MOSFETs
SAN JOSE, USA: Fairchild Semiconductor brings designers of power supplies, lighting, display and industrial applications a new generation of 600V Super-Junction MOSFETs -SupreMOS.
The combination of their low RDS (ON) and total gate charge brings a 40 percent lower Figure of Merit (FOM) compared to Fairchild’s 600V SuperFET MOSFETs. These devices, the 165-milliohm-maximum FCP22N60N, FCPF22N60NT and FCA22N60N, and the 199-milliohm-maximum FCP16N60N and FCPF16N60NT offer best-in-class reverse recovery characteristics di/dt and dv/dt bringing higher reliability for resonant converter, LLC and phase-shifted full-bridge topologies found in switch mode power supply (SMPS) designs.
Compared to SuperFET MOSFETs, these 600V Super-Junction MOSFETs offer a low gate charge for the same RDS(ON), offering excellent switching performance and delivering 20 percent less switching and conduction losses, resulting in higher efficiency.
They provide low input and output capacitances, improving efficiency at light load conditions. These features enable power supplies to meet ENERGY STAR 80 PLUS Gold classification for desktop PCs and Platinum classification for servers.
These products are part of Fairchild’s comprehensive portfolio of MOSFETs that offer designers a wide range of breakdown voltages (-500V to 1000V), state-of-the-art packaging and industry-leading FOM to deliver efficient power management anywhere electronic power conversion is needed.

Fairchild intros lowest RDS(ON) 20V P-channel MOSFET
SAN JOSE, USA: Fairchild Semiconductor brings designers of cell phones, medical, portable and consumer applications the industry’s lowest RDS(ON) (75mΩ at -4.5V) 20V P-channel MOSFET in a 1mm x 1mm WL-CSP package.
The FDZ371PZ is designed with Fairchild’s proprietary PowerTrench process technology. This technology yields an exceptionally low RDS(ON), minimizing conduction losses. Through these lower losses, the FDZ371PZ improves efficiency and extends battery life for portable designs. It also provides robust ESD protection of 4.4kV to protect against adverse ESD events.
The FDZ371PZ’s WL-CSP package utilizes 4 x 250µm lead-free solder balls, providing excellent electrical and thermal resistance values. Package height, when mounted, is an industry-leading 0.4mm.
The FDZ371PZ is part of a comprehensive portfolio of advanced MOSFETs that answer the industry’s need for compact, low-profile MOSFETs, offering high efficiency and excellent switching performance.
The price (each, 1k pcs.) is $0.30, and samples are now available. Delivery takes eight to 12 weeks.

Fairchild intros first camera isolation switch for portable devices
SAN JOSE, USA: Fairchild Semiconductor brings designers of 3G smartphones, netbooks, set-top boxes and notebooks the industry’s first image module switch that isolates parasitic components to maintain signal integrity.
The FSA1211 is a 12-port, single pole, single throw (SPST) analog switch that isolates the high speed bus from parasitic components in dual camera applications. Smartphones feature dual cameras and as these cameras move to higher and higher resolutions, parasitic components play a critical role in deteriorating signals and generating unwanted EMI.
With a bandwidth in excess of 720MHz and high ESD (5.5 kV), the FSA1211 offers an optimal way to isolate capacitance and maintain signal integrity for high speed data paths. In addition, when isolating the unused parallel interface, the FSA1211 reduces the radiated EMI of the path, improving RF desense.
The traditional parallel solution can deteriorate the signal due to the unwanted “stub,” resulting in image degradation of the camera module. Another approach is to use three analog switches, which complicates design and adds to the overall bill of material (BOM) costs. In contrast, the FSA1211 offers robust isolation and ease of design at a lower cost.
The FSA1211 complements Fairchild’s comprehensive offering of switch products used in portable and consumer applications. These analog, audio, video and USB switches are instrumental in minimizing redundant circuitry, eliminating connectors, simplifying design and conserving space in designs. Offered in a variety of functions, configurations, packages and performance levels, Fairchild’s switches are pivotal in solving portable and consumer design challenges.
