Fairchild Semiconductor (NYSE: FCS), continues to meet
customers’ needs for a compact, flexible solution that saves power
while enabling more features in today’s battery-operated, portable
electronics. The FAN5341 is a highly efficient LED driver solution
that improves brightness and resolution in portable designs, while
offering 32 linear dimming steps and driving up to five white LEDs
in series. By driving the LEDs in series this device ensures that
all the LEDs used in applications such as mobile handsets, digital
still cameras, GPS devices, MP3 players and other applications
using small LCD displays have equal brightness.
This boost LED driver operates at 1.2MHz switching frequency,
and integrates a Schottky diode to minimize the size of the
external passive components and overall board space. With the
FAN5341’s simple single-wire interface, a designer can easily
control the brightness levels of the LEDs by transmitting digital
pulses from the microcontroller to the FAN5341. And since this
lighting solution drives three to five LEDs in a series, the same
current flows through each LED to ensure equal brightness. This LED
driver also addresses space and power considerations in portable
designs since it offers up to 83 percent efficiency, minimizing
power consumption. The FAN5341 is assembled in a compact, low
profile 2mm x 2mm UMLP package.
The FAN5341 is the newest addition to Fairchild’s portfolio of
lighting solutions for portable applications. Fairchild continues
to drive innovation in the lighting area by developing
market-driven products that lower the overall solution cost, while
providing excellent performance.
