dimming. The switching frequency is adjustable in the range of 200 kHz to 700 kHz. The adjustable soft start feature limits the current peak as well as voltage overshoots at start-up. LED system cost reduction with LITIX Power TLD5190QV The LITIX Power family of DC/DC converters and controllers targets medium-power to high-power applications. These comprise LED daytime running lights and LED low-beam and high-beam. The new family member TLD5190QV is a synchronous H-bridge DC/DC controller with similar features as the TLD5541- 1QV. Without SPI interface it particularly suits LED control electronics where no microcontroller is needed, while it is easy to implement. The device also offers integrated protection functions, both analog and digital (PWM) dimming and an adjustable switching frequency in the range of 200 kHz to 700 kHz. Availability and packaging The synchronous H-bridge DC/DC controllers TLD5541- 1QV TLD5190QV are already in volume production and available in VQFN-48 packages. Both LED drivers are suitable for use in harsh automotive environments and specified according to AEC-Q100. Infineon supports the design-in with demo boards, data sheets and PSpice simulation models. Further information on the complete LITIX portfolio is available at www.infineon.com/LITIX

interface and signal conditioning – to introduce a comprehensive development resource for the wearable electronics sector. The newWearable Development Kit (WDK1.0) combines a wide array of highly optimized components, with the objective of assisting OEMs in bringing differentiated products to market. Using it can significantly accelerate design cycles for wearable electronics while mitigating heavy engineering costs. “Despite the growing interest in wearable electronics, to date there is simply not a solution on the market that provides the scope needed by OEMs to help them develop feature rich designs that will attract strong consumer uptake,” states AJ ElJallad, senior manager, corporate strategy and business development at ON Semiconductor. “The WDK1.0 is a multi-faceted design asset that will allow wearable technology projects to be expedited – shortening time to market and curbing the associated investment in engineering by leveraging the extent of ON Semiconductor’s product portfolio.” For this new offering, a high efficiency programmable NCP6915 Power Management IC provides 5 LDOs and 1 DC-DC to support power requirement for the smartwatch and for additional development requirements. An NCP1855 battery charger IC, plus an LC709203F fuel gauge and a 10 watt (W) rated SCY1751 wireless charging front-end controller (supporting AirFuel compatible magnetic resonance charging) have also been incorporated. The kit’s sensor capabilities stem from the MEMS-based FIS1100 inertial measurement unit (IMU), with 3‐axis gyroscope and 3‐ axis accelerometer operation enabling accurate multi- dimensional motion tracking. There is also an embedded temperature sensor included and an LC898301 driver IC for initiating haptic feedback. Critical to the WDK1.0 is its wireless connectivity, which is addressed via an ultra-lower power nRF52832 multi-protocol system-on-chip (SoC) from Nordic Semiconductor. This features a 32-bit ARM® Cortex™ processor core and a 2.4GHz transceiver – offering support for Bluetooth Low Energy (BLE) and other relevant wireless technologies. The kit is complemented by a SmartApp which can be downloaded directly from Android PlayStore and Apple AppStore. Using this, various pieces of information can be transposed, such as the steps taken, calories burnt, distance covered and activity period, as well as human machine interface aspects like screen brightness adjustment, clock face control, alarm settings and establishing fitness goals.
