Technology Corp.'s H-grade version of the LTC3872 has a small footprint 550kHz fixed frequency step-up dc/dc controller
that is specified over a -40
to150C junction temperature range. The LTC3872 accepts a 2.5 to 9.8V input
voltage range and can produce an output voltage as
high as 60V without needing a sense resistor. Capable of driving large
N-channel MOSFETs, the LTC3872 can produce high peak output currents. When
powered with a 5V bias voltage, the switch can go
up to 60V, making it well suited
for automotive, heavy equipment and industrial control applications.
current-mode architecture provides cycle-by-cycle current limiting and
transient response. Pulse skipping operation at light loads reduces the
quiescent current to 250uA which helps extend the run-time in the battery-powered
applications during standby mode. Additional features include an internal
soft start, adjustable current limit, precision undervoltage lockout and tight
±1.6 percent reference voltage accuracy over the full -40 to 150C operating
temperature range. The LTC3872H is offered in a
thermally enhanced 2mm x 3mm DFN-8 package and 8-lead ThinSOTTM package. 1,000-piece
pricing starts at $2.35 each.

We’ve collected photos of “dream cars” from the Geneva Motor Show, as well as from the recent auto shows in Detroit and Chicago. From Maserati and Lamborghini to Chevy and Toyota, we offer a few of the recent standouts.
Boston-based Cambrian Innovation has developed a solution called EcoVolt that uses bioelectrochemistry to treat wastewater so it can be turned into electricity. The company is targeting the beverage industry to convert waste from making beer and wine into energy breweries and wineries can use to run their operations.
CRP Technology has 3D-printed a 1:14 scale model of a yacht in carbon fiber composites to demonstrate the possibilities and give a boost to boat design. The material and process are also used for under-hood motorsport applications and in aerospace.
