Harnessing tiny amounts of ambient energy from sustainable sources works well in theory, but are there any practical solutions to achieving it? By Tony Armstrong, Director of Product Marketing, Linear Technology.

Elegant, single-IC power management solutions are readily available for many portable devices, such as smartphones or tablets, which operate at low voltages and low power levels. Power management solutions for high power and high voltage systems, such as those required for many industrial or medical devices, generally require cumbersome, specialised discrete component solutions. In these environments, the LTC4020 simplifies power management by in...

Linear Technology’s SmartMesh IPTM wireless sensor networking products now provide the ability to programme industrial IoT applications directly on the embedded ARM Cortex-M3, running Micrium’s µC/OS-II RTOS. Users no longer need a separate processor for sensor interface and edge data analytics, reducing the cost, footprint and power consumption of the integrated wireless sensor node. 

The LT3748, a high input voltage isolated flyback DC/DC controller developed by Linear Technology, is now available in a military MP grade version. This device simplifies the design of an isolated DC/DC converter by not requiring an opto-isolator, third winding or signal transformer for feedback since the output voltage is sensed from the primary-side flyback signal. 

The LTC4412, a PowerPath controller developed by Linear Technology, is now available in high reliability and military temperature grade versions. The device permits low-loss ORing of multiple input DC power sources. Its 20mV forward voltage is at least 10 times lower than that of a Schottky diode. As a result, the device increases efficiency by an order of magnitude, due to much lower power loss and less self-heating in systems requiring automati...

At APEC 2015, which takes place from 16th to 18th March at the Charlotte Convention Center in Charlotte, NC, Linear Technology will demonstrate its latest high performance analogue technology and power products.

Featuring fast rise and fall times of 1.2ns and a toggle frequency of 280MHz, the LTC6752 family of comparators has been introduced by Linear Technology. Designed for driving logic levels from 3.3V down to 1.8V, the devices exhibit only 2.9ns of propagation delay and overdrive dispersion of only 1.8ns. 

A dual input, wide voltage range synchronous buck-boost DC/DC converter, with an integrated low loss PowerPath control, has been released by Linear Technology.

The LT8570 and LT8570-1, current mode, fixed frequency step-up DC/DC converters, have been announced by Linear Technology. The LT8570 uses an internal 500mA, 65V switch, whereas the LT8570-1 uses a 250mA, 65V switch. Both devices operate from an input voltage range of 2.55-40V, making them suitable for applications with input sources ranging from a single-cell Li-Ion to automotive inputs.

Linear has announced the LTC7860, a high efficiency switching surge stopper with overvoltage and overcurrent protection for high availability systems. During normal operation the LTC7860 turns on an external P-channel MOSFET continuously to pass the input voltage through to the output with minimum conduction loss.
