SINGLE-STAGE PFC PRIMARY SIDE REGULATION LED DRIVERS
Advantages
Simplify Design Complexity
in LED Lighting Applications
• Minimizes BOM
for smaller lamp size
Implementing dimming capabilities in a conventional TRIAC dimmer
infrastructure is challenging because of compatibility issues. Additionally, small
space requirements remain a consideration in ≤20W LED lighting applications.
To address these obstacles, Fairchild developed the FL7730 single-stage
primary side regulation (PSR) controller with power factor correction (PFC),
TRIAC and analog dimming compatibility, as well as the FL7732 for
non-dimmable applications.
• Accurate Constant Current
(CC) control, independent
online voltage, output voltage
and magnetizing inductance
variation
To improve power factor (≥0.9) and THD (Class-C), both devices feature constant
on-time control with an internal error amplifier and low bandwidth compensator.
Precise Constant Current accuracy/control (±5%) regulates accurate output
current, independent of input and output voltage, allowing designers to achieve
high and improved lighting quality.
• Excellent PF (≥0.9)
• Low THD (Class-C)
• Power efficiency ≥85%
• Linear frequency control
for better efficiency and
simple design
• Open-LED protection
• Short-LED protection

CLASS-D AUDIO AMPLIFIER
Advantages
• Low EMI design allows
filterless operation
• High noise rejection using
differential audio inputs
• High efficiency boost regulator
provides higher output power
over battery voltages
Achieve Loud and Clear Sound
While Extending Battery Life
Customer demand is driving the need for louder and clearer speaker
sound in mobile devices. While minimizing impact on battery life,
designers can achieve the performance they require with Fairchild’s
FAB3103. The 2.3W Class-D audio amplifier with integrated boost
regulator and battery automatic gain control (AGC) allows for
high audio output power over a power supply range of 2.5V to 5.2V from a 3.6V
Li-Ion battery.
• Boost shutdown at lower
output power increases
efficiency and reduces
quiescent current
consumption
At low power output, the device’s boost regulator automatically shuts down
for greater efficiency and lower quiescent current consumption, resulting in
longer battery runtime. The FAB3103 audio amplifier also features battery
AGC that reduces gain when the power supply voltage is low in order to limit
maximum power consumption, reducing distortion and preventing early device
software shutdown.
• AGC monitors battery voltage
and dynamically adjusts gain,
extending battery runtime
Available in a 12-bump, WLCSP, the FAB3103 device also offers several
protection features including short circuit protection, low voltage shutdown, and
click-and-pop suppression.

AUDIO JACK DETECTION SWITCH
Advantages
• Detects two different
audio jack configurations
• Enables use of all existing
headsets in new devices
without manual configuration
• Automatically routes GND
and MIC to audio jack
terminals
• Ability to detect 3- or
4-pole audio accessories
Meet Audio Standards with a Single Device
Designers no longer have to choose supporting one audio jack configuration
standard (OMTP or CTIA) over the other, or rely on a more complex design
with additional components. Fairchild's FSA8049 MIC/GND cross point switch
detects two different audio jack configurations and connects properly to each
standard, enabling the use of all existing headsets in new devices without manual
configuration. This functionality allows the end-user to plug accessories, such as
headsets, with different audio pole configurations into the device and have them
operate correctly. The FSA8049 is available in a space-saving 9-ball WLCSP
1.16mm x 1.16mm package.

Low Package Height,
Critical for Small Space Designs
Now designers can reduce space and simplify board layout with Fairchild’s new
series of MicroDIP bridge rectifiers. With the ability to increase reliability and
lower overall manufacturing costs, the series provides one of the lowest package
heights for 1A bridge rectifiers. The MDBxS family meets the need for small
space design solutions critical for mobile device battery chargers, power adapters
and Power-over-Ethernet (PoE) devices including IP surveillance cameras. The
family currently consists of three parts—MDB6S (600V), MDB8S (800V) and
MDB10S (1000V), with 50V – 400V versions in development.

SURFACE MOUNT PACKAGE SCHOTTKY RECTIFIER
Advantages
• Low profile, surface mount
package: SMB/DO-214AA
• High reverse voltage:
VRRM = 200V
• Low power loss,
high efficiency
• High surge current:
IFSM = 80A
Schottky Rectifier Offers High Reverse Voltage
and Smaller Surface Mount Packages
Designers of power supplies for industrial, wireless infrastructure and alternative
energy systems no longer have to trade off between a high reverse voltage and
a small surface mount package when choosing a rectifier. The S320 Schottky
rectifier offers both a maximum repetitive peak reverse voltage of 200V and a
low profile, industry-standard, mini surface mount package (SMB/DO-214AA).
With a maximum forward voltage of 0.9V, the S320 has lower power loss than
similar standard silicon rectifiers resulting in a higher overall power efficiency
of the power supply. In addition, the S320 has a wide operating temperature
range of -65ºC to +150ºC. The S320 is just the latest addition to Fairchild’s broad
portfolio of Schottky rectifiers.

ENGINEERING CONNECTIONS
New Semiconductor Solutions Meet the Challenges of
Efficient and Effective Generation of Renewable Power
The following article is an abridged version with sections from Fairchild’s backgrounder on solutions for the generation of renewable power.
Challenges Facing Solar Power Generation
Higher cell efficiency, lower system costs, reliability and
geopolitical systems all pose challenges to this market’s
growth. The cost of a solar electric system is represented as
dollar/watt. The current cost of a utility based solar electric
system is $3.3/W (Source: DOE). Government programs
are funding research to help drive down the cost to $1/W to
help this market expansion. The different cost components
that make up this system cost are provided in figure below.
The panels represent more than 50% of the system cost; the
balance of system (BOS) represents 43% and solar inverters
represent 6%. In order to reach the aggressive $1/W target,
advancement in all PV system components is compulsory.
Power electronics, while a small portion of the total cost,
will drive harvesting efficiency and therefore is critical.
Reaching Cost Reduction Targets will require
advances in all PV system components

Component Choices for Efficient, Cost-Effective
and Reliable Implementations
Regardless of which topology is used, designers must make
careful choices when selecting the individual components.
The necessary improvements in performance, cost, reliability
and efficiency require special attention to the following
factors and their ultimate impact on the overall system:
Component count:
cost, size, total power dissipation, reliability
Heat/thermal management:
reliability, size/weight, cost
Minimization of losses and parasitics:
system performance, total power dissipation
Fairchild is committed to the development of components
that will help designers implement systems optimized for
these three important factors. Key building blocks for future
harvesting and conversion implementations include:
• IGBTs, and high- and mid-voltage MOSFETs
(high-voltage includes SuperFET®, SuperFET® II
and SupreMOS® MOSFETs; mid-voltage MOSFETs
incorporate PowerTrench® technology). These
products feature high current handling capability and
low conduction and switching loss.
• Gate drivers, with a wide range of options that include
optically isolated; high-speed low side; and high-voltage.
• Bypass and blocking diodes that maximize energy
prevent energy loss in storage systems.
Panel manufacturers have made significant progress in
cost reductions through new manufacturing processes and
improvements in the conversion efficiencies of the solar cells.
As the panel costs drop further in the future, the BOS and
Solar Inverter costs will become a dominant part of the total
system cost.
• High-voltage silicon carbide (SiC) devices that
offer significant improvement on both cost and
efficiency in energy conversion systems as well as
higher reliability.

online seminars and podcasts that help designers
solve their design challenges and speed timeto-market. Get the latest information at
