Bright ideas for LED applications
At NXP Semiconductors, we have a portfolio filled
with bright ideas for LED applications. We design
for high performance and lower overall cost,
focusing on power efficiency and flexible design-in.
As the world’s leading provider of products based
on the I2C-bus, we work closely with our customers
and partners to develop next-generation LED
solutions. That means you get options like Fastmode Plus, a wide supply range (2.3 to 5.5 V),
and flexible PWM functions. It also means ultralow standby modes (<1 µA), lower overhead on
the CPU, and extended battery life in mobile
applications.

C-bus enables easy system modification and designs that are easy to scale
4 Voltage-switch PWM dissipates current in external resistor to reduce on-chip heating
4 Long-distance communication is easy to implement
4 Individual addresses are available, as are programmable sub-calls. That means groups of
devices can responds to the same software commands, and thus reduce overhead
4 Bus controllers and bus buffers make it easy to combine the I
We even give you a head start on design, with
application boards and daughter cards, and have
an established manufacturing infrastructure that
supports very high volumes.
It’s everything you need to make lighting
affordable, in everything from mobile handsets and
gaming systems to outdoor billboards, signage, and
more.
The table below provides an overview of the special
benefits we bring to specific LED applications. The
rest of the brochure highlights key products in the
portfolio.

4 Up to 30% longer battery standby times
4 Ultra-low power consumption in standby modes (< 1 µA)
4 Memorizes complex blink patterns, offloads CPU
4 Lower-cost, drop-in replacements for Silicon Touch ST2221A and
STMicroelectronics STP08CDC596
4 Ample manufacturing capacity for high-volume production
4 Very low power surge, due to staggered ON time, which reduces EMI
4 Supports driving external FETs or switched-mode regulators, for higher voltage/
current LED strings
4 External clock input supports device synchronization, to eliminate noise and artifacts
4 Simple I2C-bus firmware
4 Offload the microcontroller, since it doesn’t have to communicate after the LED is programmed,
and it doesn’t have to manage LED power
4 Unused bits can be put to use as GPIO
