New NXP Radio IC SAF4000
Quick Facts:
NXP radio designs are in 19 of the top 20 tier-1
automotive offerings delivering more than 500 million
car radios in the past 10 years. NXP continues to offer
world class integration of RFCMOS and SDR (Software-
Defined Radio).
NXP has delivered 400 million car amplifiers in the past
10 years. The new TDF8534 is the market’s first full
digital amplifier. It has the smallest footprint available for
five channels.
multimedia processors have been deployed in
over 65 million vehicles. 8 is a highly scalable,
powerful application processor family designed to
advance the multimedia experience in future connected
cars. Samples are available. Customers using 8
+ SAF4000 will benefit from a full NXP solution with
reference design and software enablement. For further

Infineon enables compact and cost-
effective LED front light applications with
LITIX™ LED driver family
LEDs in automotive front lighting enable energy
savings, new light designs and applications such as
matrix beam and laser high-beam. Supporting the
progress in automotive lighting Infineon Technologies
AG (FSE: IFX / OTCQX: IFNNY) launched high-power
LED drivers specifically designed for automotive front
lights. The drivers are available within the new LITIX
Power Flex series and the LITIX Power series. They
address flexible DC/DC driver solutions supporting LED
systems of up to 50 W and even above. Application
setups can vary: many medium-power LEDs with string
voltages of up to 55 V or few LEDs with high currents of
up to 3 A and more.
Both LED drivers, the LITIX Power Flex TLD5541-1QV
and the LITIX Power TLD5190QV, are well-suited for
high-power and high-current LED applications. These
include for example front lighting, laser and LED
headlamps. They also suit high-efficiency supplies
for LED applications working on battery voltage.
Furthermore, they allow cost-optimized full-LED front
light applications for cars and even motorcycles with
their space limitations in the handlebar’s headlamp.
Maximum LED system efficiency with LITIX Power Flex
TLD5541-1QV
The TLD5541-1QV is a first available member of the
newmulti-topology DC/DC controller family LITIX Power
Flex. The synchronous H-bridge DC/DC controller is
ideal for driving all high-power LED configurations with
maximum system efficiency of well above 92 percent.
This results in higher reliability and improved thermal
behavior and reduced PCB size. Thanks to its optimized
spread spectrum switching frequency, the TLD5541-
1QV helps reduce EMC emissions to fulfill challenging
EMC requirements like CISPR 25 class 5.
The TLD5541-1QV features seamless buck-boost
regulation and fast dynamic load jump behavior.
Therefore, it enables cost-optimized LED headlamps
with complete protection and diagnosis features. Just
one TLD5541-1QV can drive two and more separately
switched LED loads in one string, with up to 55 V string
voltage. The LED current accuracy is specified with +/-
3 percent.
The TLD5541-1QV with built-in protection features
and SPI interface offers both analog and digital (PWM)
