At the low end of the power spectrum are the nanopower conversion requirements of energy harvesting systems such as those commonly found in IoT equipment, which necessitate the use of power conversion ICs that deal in very low levels of power and current. These can be tens of microwatts and nanoamps of current, respectively. Tony Armstrong, Director of Product Marketing Power Products, Linear Technology Corporation explains.

Enabling battery-powered, high performance broadband transmitters operating from 700MHz to 6GHz, Linear Technology introduces a low power I/Q modulator. The LTC5589 is powered by a single 2.7 to 3.6V supply and draws only 29.5mA current. According to the manufacturer, this is 50% lower power consumption than other solutions.

Driving an all N-channel synchronous power MOSFET stage, the LTC3896 high voltage inverting switching regulator controller has been unveiled by Linear Technology. Most low to medium power inverting DC/DC converters utilise a coupled inductor or transformer. However, the LTC3896 uses only a single inductor and converts a 4V to 150V positive input voltage to a regulated negative output voltage from -60 to -0.8V at output currents up to 15A.

A 16-bit, 5MS/s SAR (Successive Approximation Register) ADC with a wide rail-to-rail input common mode range, the LTC2311-16, has been introduced by Linear Technology. The LTC2311-16 features a flexible differential input that accepts analogue signals up to the Nyquist frequency. This provides direct conversion of a variety of signal types while maintaining a good SNR of 81.6dB with a 2.2MHz input signal and achieving a high CMRR of 85dB for the ...

Driving an all N-channel MOSFET power stage, the LTC3895 high voltage non-isolated synchronous step-down switching regulator controller has been unveiled by Linear Technology. Its 4 to 140V (150V absolute maximum) input voltage range is designed to operate from a high input voltage source or from an input that has high voltage surges, eliminating the need for external surge suppression devices.

Linear Technology announces the LT8304, a monolithic flyback regulator that significantly simplifies the design of isolated DC/DC converters. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator or third winding for regulation.

Linear Technology Corporation announces the availability of a low loss 3-phase suitable diode bridge rectifier reference design, demonstrated on evaluation board DC2465. Conventional 3-phase rectifiers employ six diodes, but the diodes drop voltage and dissipate significant power at just a few amperes of load current. This requires costly heat sinking and active cooling solutions that complicate thermal design and increase solution size.

Supplied in a compact 9x11.25x4.92mm BGA package, the LTM4642 dual 4A or single 8A step-down µModule regulator has been unveiled by Linear Technology. The device operates from a 2.375 to 20V input voltage range and regulates two output voltages adjustable from 0.6 to 5.5V.

This week’s Hannover Messe will see Scienlab present its engineering services and products for the entire development chain of battery management systems (BMS) on Linear Technology’s stand – H23, Hall 9.

VersaSense will present live demonstrations of its award-winning MicroPnP product range at Hannover Messe, Linear Technology Stand H23, Hall 9.

Vicotee AS, part of the Virinco Group, announces the release of Vicotee - a wireless mesh IoT sensor interface which utilises SmartMesh IP from Linear Technology Corporation. Launching officially at Linear Technology’s booth H23-Hall 9 at the Hannover Fair 2016 Exhibition, this innovative IoT solution provides a vast array of opportunities for increased control and efficiency of physical infrastructure, made possible through the collection ...

Designed for automotive, industrial and avionic systems, Linear Technology introduces the LTC4380 ultralow quiescent current (IQ) surge stopper. The LTC4380 replaces traditional shunt circuits composed of bulky inductors, capacitors, suppressors and fuses with a simple IC and series N-channel MOSFET solution to offer compact overvoltage and overcurrent protection for always-on 4 to 72V electronics.

The new LT8608 from Linear Technology is a 1.5A, 42V input synchronous step-down switching regulator with synchronous rectification topology that delivers 93% efficiency while switching at 2MHz. This enables designers to avoid critical noise sensitive frequency bands, such as AM radio, while using a very compact solution footprint. Burst Mode operation keeps quiescent current under 2.5µA in no-load standby conditions making it well suited f...

Linear introduces the LTM4632, a triple output µModule regulator for powering all three voltage rails of the new QDR4 and older DDR SRAM: VDDQ, VTT and VTTR (or VREF). Housed in a miniature, lightweight, ultrathin LGA package (6.25x6.25x1.82mm), the LTM4632 can be soldered on the backside of the PCB, and with one resistor and three capacitors it occupies only 0.5cm² (dual-) or 1cm² (single-sided).

Linear Technology Corporation introduces the LTC2876 and LTC2877, exceptionally rugged, high voltage tolerant RS485 transceivers targeted for PROFIBUS-DP (decentralised periphery) master and slave devices. As with any fieldbus, PROFIBUS-DP systems are prone to installation cross-wiring faults, ground voltage faults, or surge, which can cause catastrophic overvoltage conditions that exceed the absolute maximum ratings of typical transceivers.

The LTC7149 is a high efficiency, 60V, 4A synchronous buck regulator for negative output voltage supplies. It incorporates a current mode architecture with user selectable internal or external loop compensation and an output voltage that is programmed with a single external resistor.

Its 4 to 60V input voltage range makes it suitable for a wide variety of applications, including automotive, industrial and architectural lighting.

Linear Technology Corporation introduces the LTC7813, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. When cascaded, its independent step-up (boost) and step-down (buck) controllers regulate the output voltage from an input voltage that can be above, below, or equal to the output voltage, including during an automotive load dump or cold crank.

Linear Technology Corporation has introduced the LTC7130, a constant frequency peak current mode synchronous step-down DC/DC converter with temperature compensated ultra-low DCR current sensing and clock synchronisation. The device’s architecture eases compensation and offers the ability to directly parallel multiple ICs for higher current capability.
