150-mA synchronous DC/DC regulators optimize light-load efficiency for factory automation and automotive applications
Texas Instruments (TI) (NASDAQ: TXN) introduced two 65-V, 150-mA synchronous DC/DC buck converters with what the company said is the industry’s lowest 10.5-uA quiescent current (IQ) for powering factory automation and automotive sensor applications requiring high efficiency.
The industrial-grade LM5165 and automotive-grade LM5165-Q1 micro-power step-down regulators feature a wide input voltage (VIN) range and dual control modes for optimizing efficiency and printed circuit board (PCB) area. By using the regulators together with TI’s WEBENCH® Power Design tool, engineers can get their factory and process automation designs to market faster. For more information, samples and an evaluation module, see www.ti.com/lm5165-pr.
SMT power inductors from TT Electronics support 180°C high temperature operation in automotive applications
TT Electronics launched a range of surface mount (SMT) power inductors for use in high temperature, high power, automotive applications. The HA72T-06 series inductors meet the growing automotive market’s demand for certified, high power inductors for high efficiency DC-DC converter deployment using high switching frequencies up to 3Mhz as well for as EMI and low pass DC ripple filters in high temperature environments.
Provides Improved Fuel Economy, Fewer Parts, Lower Weight and Reduced Costs
Better fuel efficiency. Fewer parts. Lighter weight. Lower costs. Reduced noise, vibration and harshness (NVH). Dayco’s newest innovation, the Dayco Vacuum Generation System, which will go into full production with a major automaker in mid-2016, continues that tradition.
The Dayco Vacuum Generation System replaces costly, heavy, fuel-consuming mechanical and electrical vacuum pumps found on many of today’s engines. Automakers will benefit from reduced weight and decreased system cost, and automakers and consumers can enjoy increased fuel economy.
Latest DSP quadruples neural network performance capability compared to previous-generation Vision DSP
Cadence Design Systems, Inc. (NASDAQ: CDNS) announced the Cadence® Tensilica® Vision P6 digital signal processor (DSP), Cadence’s highest-performing vision/imaging processor, which extends the Tensilica product portfolio further into fast-growing vision/deep learning applications areas.
New instructions, increased math throughput and other enhancements set a new standard in imaging and computer vision benchmarks, increasing performance by up to 4X compared to the Tensilica Vision P5 DSP.
Linear Technology Corporation introduced the LTC4380, an ultralow quiescent current (IQ) surge stopper, providing compact overvoltage and overcurrent protection for always-on 4V to 72V electronics in automotive, industrial and avionic systems.
The LTC4380 replaces traditional shunt circuits composed of bulky inductors, capacitors, transient voltage suppressors (TVS), and fuses with a simple IC and series N-channel MOSFET solution, saving board space and enabling continuous operation through transient voltage or current surges. The LTC4380 protects downstream electronics from input overvoltage up to the MOSFET rating, while also protecting the power supply from output overload. Device current consumption is a mere 8µA in normal operation and 6µA in shutdown mode, prolonging battery run and standby time. The low current allows a large filtering resistor to the device supply pin, enabling operation through automotive cold crank and overvoltage transients above 100V.
Allegro MicroSystems, LLC introduced two new adjustable high-frequency DC-DC step-down switching regulators with an integrated high-side power MOSFET ideal for power supply requirements of the latest infotainment systems.
Allegro’s A8586 provides up to 3.5 A output current, while the A8587 has output current of up to 2.0 A. Both devices are automotive, AEC-Q100 qualified and incorporate current-mode control for fast transient response. The wide input range of 3.8 to 36 V makes both devices suitable for a wide range of step-down applications, including those in an automotive input environment. Battery-driven “keepalive” applications benefit from the low 30 μA operational quiescent current. Both devices are designed to robustly handle a load dump condition with 40 V maximum rating as well as idle-stop and cold crank conditions with 3 V UVLO rating.
Vishay Intertechnology, Inc. (NYSE: VSH) introduced two new AEC-Q101-qualified surface-mount transmissive optical sensors for automotive and industrial applications. Offered in a compact 5.5 mm by 4 mm by 5.7 mm package, the Vishay Semiconductors single-channel TCPT1600X01 and dual-channel TCUT1600X01 feature an increased dome height compared with previous-generation devices.
Substantial reductions in nitrogen oxide emissions are also required by the US SULEV 30 emissions standard. A close-coupled annular catalytic converter developed by Continental supports near-complete NOx conversion in turbocharged gasoline engines
