SINGLE-CHIP PWM SOLUTION
Advantages
• Proven, reliable mWSaver™
Technology
• Achieves <30mW no load/
standby power consumption
• Reduces up to 15 external
components
Applications
• Notebooks
• Game consoles
• Printer adapters
• LCD TVs
Single-Chip PWM Solution Saves Board Space
Designers who need to achieve lower standby power consumption in devices
such as notebooks, printers, LCD TVs, now have an industry-leading single-chip
solution with Fairchild’s FAN6756. Lower standby power in 75W spaceconstrained applications is achieved without additional external circuitry, complex
designs or higher costs. The single-chip solution is a highly integrated greenmode PWM controller that significantly reduces standby losses in SMPS designs,
and eliminates up to 15 external components.
The FAN6756 also includes an innovative AX-CAP™ discharge method that
minimizes losses in the EMI filter stage, while meeting the IEC61010-1 safety
requirement. This functionaity is achieved by eliminating the X-cap discharge
resistors and discharging X-cap energy through the HV pin when the power is
unplugged from the AC outlet.
Ideal for power supplies that demand extremely low standby power, the FAN6756
incorporates mWSaver™ Technology. This technology allows the device to reduce
power losses not only in the controller, but also in the external circuits and
components. It also includes a proprietary deep burst mode technology that
reduces switching loss at no-load and light-load conditions.

OptoHiT™ PHOTOTRANSISTOR OPTOCOUPLERS
Advantages
• Excellent CTR linearity at
high temperature
• CTR at very low input
current, IF (1mA, 1.6mA,
and 3mA)
• Small footprint: half-pitch
mini-flat package (MFP)
saves board real estate
for more flexibility and
overall systems cost savings
Reliable Isolation and Minimized System
Failure with OptoHiT™ Optocouplers
Realize increased design margins and stable parameters in high temperature
environments with Fairchild’s new FODM8801 OptoHiT™ high temperature phototransistor optocoupler. You’ll achieve high noise immunity and reliable isolation
at high operating temperatures, up to 125°C, as this new series implements
Fairchild’s proprietary OPTOPLANAR® coplanar packaging technology. In addition, the FODM8801 offers excellent CTR linearity and operates at a very low
input current (IF). The optocoupler consists of an aluminum gallium arsenide
(AlGaAs) infrared light emitting diode optically coupled to a phototransistor.
Because the FODM8801 is packaged in a compact, half-pitch, mini-flat, 4-pin
package (1.27mm lead pitch), benefits also include board space savings and
design flexibility, ultimately allowing for overall reductions in system cost.

LED LAMP DRIVER IC
Advantages
• High functional density in a
small form factor
• Up to 60% board space
savings compared to other
solutions
• Up to 20% lower bill of
material costs compared
to other solutions
• Digital power factor (PF)
realization greater than 0.9
• Lower total harmonic
distortion (THD)
• 90% electrical efficiency
• Meets worldwide Energy Star®
regulations
Small-Spaced Dimming Challenges Solved
with LED Lamp Driver IC
With Fairchild’s FL7701 smart non-isolated Buck LED driver with power factor
correction, designers attain efficient dimming solutions that also fit within existing sockets. Because the need to work reliably in a small space while providing
high efficiency is imperative, the device uses a digital technique that allows it to
automatically detect the AC input voltage condition. A special internal reference
signal is then created, resulting in high power factor correction. The FL7701 will
work from a DC input voltage condition, automatically sensing AC versus DC
input voltage conditions. It also combines high functional density to create the
smallest form factor and allows designers to save up to 20% BOM costs and up
to 60% board space savings.
The LED driver provides energy savings that meet the most stringent worldwide
regulations, such as Energy Star®. Designers also benefit from the high degree
of integration offered by the FL7701. The result is increased luminary lifespan
to more than five years (current solution only achieves three years.) And reliability is also improved since no electrolytic capacitors for the input, output or
the FL7701 VDD supply are required.
Applications
• Decorative lighting
• Low-power lighting

integrated device that includes a proprietary burst-mode function with low
operation current and minimizes standby power consumption.
• The dual switch flyback solution for 75W~230W applications and consists
of the FAN6920MR integrated critical mode PFC and quasi-resonant
current mode PWM controller, the FAN7382 gate driver, in tandem with
the FAN6204 secondary synchronous rectifier controller for flyback
topology and forward freewheeling rectification.

N-CHANNEL PowerTrench® MOSFET
Advantages
• Provides lower conduction
losses, max RSS(ON) = 16.5mΩ
at VGS = 4.5V, ID = 8A
• 40% smaller than legacy
solutions
• MicroFET 2mm x 3mm2
• RoHS Compliant
• HBM ESD protection >2kV
Applications
Improve Battery Life, Reduce Space
in Li-Ion Battery Pack
For mobile applications that use a one-cell Li-Ion battery pack, Fairchild’s
FDMB2307NZ dual N-channel PowerTrench® MOSFET, addresses design
space and efficiency challenges. The device enables bidirectional current flow,
and by using advanced PowerTrench processes, the FDMB2307NZ provides
high power density and a maximum RSS(ON) of 16.5mΩ at VGS = 4.5V, ID = 8A.
This results in lower conduction losses, lower voltage drop, less power
dissipation and increased overall design efficiency when compared to
competitive solutions.
Designers will also benefit from excellent thermal performance, resulting in
cooler system operation, further increasing efficiency. The device’s small package size (MicroFET 2mm x 3mm2) provides one of the smallest MLP solutions
available—40% smaller than existing legacy solutions—saving significant board
space in their design.
