), or TI, recently unveiled the industry's first floating switch
architecture to simplify offline LED drive design. The floating
switch architecture with TI's TPS92411 requires no inductive
components for power transfer, thus lowering cost and simplifying
design at the same time.

LED lamps most commonly feature flyback, buck and boost
converters' SMPS technologies, which operate at high frequencies,
need inductive components and expensive custom components. The
implementation of phase dimming therefore requires multiple
iterations. TI's solution is targeted at achieving fade LED
lighting within a fixed voltage range and without the use of
inductors or isolation transformer.
TI's constant endeavor to develop products targeting different
applications such as microcontroller, factory automation, smart
grid, high-voltage power, and LED lighting and control should
help it grow revenue even as it moves away from some traditional
In the third quarter of fiscal 2013, TI generated revenues of
$3.24 billion that were up both sequentially and year over year.
The Analog business grew 10.7% sequentially and 4.8% year over
year. All product lines contributed to the sequential increase in
analog revenues although power management products saw the
strongest increase. TI attributed the year-over-year increase to
very strong SVA sales, supported by somewhat higher HPA and power
management and flattish HVAL.
