TECHNOLOGY IN ACTION ADVERTORIAL
150VIN & VOUT Synchronous 4-Switch Buck-Boost Controller with Integrated Switching Bias Supply
Easy locking connector from binder cannot be mis-mated

inder, an industry and technology leader in circular connector solutions for factory automation, announces
an easy locking connector system (ELC). Designed for a wide variety of applications in the
critical area of medical systems, the binder ELC series 570 has an intuitive locking system to ensure positive mating and mis-mating is prevented thanks to a mating position clearly defined by the “shape” of the mating area. The new binder ELC series 570 connector features a
PA66 plastic housing, has 12 gold plated contacts for 0.25mm² wires and is rated at 2A, 150V. binder has designed the connector to be good for more than 5000 mating cycles which is sure to satisfy the operating requirements of most applications across the medical sector. The female panel mount connector provides protection against the ingress of liquids, water splash and accidental electrical contact and, when mated, the new easy locking connector offers protection to IP54.

150V high efficiency (up to 99%) 4-switch synchronous buck- boost DC/DC controller, which operates from input voltages above, below or equal to the regulated output voltage. Its 4.5V to 150V input voltage range operates from a high input voltage source or from an input that has high voltage surges, eliminating the need for external surge suppression devices, ideal for transportation, industrial and medical applications. To prevent high on-chip

power dissipation in high input voltage applications, the LTC3777 integrates a low quiescent current high efficiency switching bias supply for its internal power consumption. The output voltage of the LTC3777 can be set from 1.2V to 150V at output currents up to tens of amps, depending on the choice of external components. Output power up to 500W can be delivered with a single device. Higher powers can be achieved when multiple circuits are configured in parallel. The LTC3777’s powerful 1.5? N-channel MOSFET gate drivers can be adjusted from 6V to 10V, enabling the use of logic-level or standard-threshold MOSFETs. The LTC3777 employs a proprietary current mode control architecture for constant frequency in buck, boost or
buck-boost modes. The operating frequency can be synchronized to an external clock from 50kHz to 600kHz, while an input/output constant current loop provides support for battery charging and overload protection. The user can select either forced continuous mode or discontinuous mode to maximize light load efficiency. Additional features include seamless transfers between operating regions, a power good output voltage monitor, adjustable soft-start and input overvoltage lockout, and output voltage disconnect during shutdown. The LTC3777 is available in a 48-lead e-LQFP package with pin skipping for high voltage spacing. Extended and industrial versions are available from –40 to 125°C.

Electronica - The event that brings the global electronics industry to Munich
E
lectronica will once again bring the global electronics industry together in Munich for the
World’s largest trade fair dedicated to all aspects of electronics technology. electronica 2018 will offer visitors the chance to see all the major players from key electronics industry sectors including semiconductors, power, interconnection, embedded and test and measurement as well as the chance to learn more about developments that are considered important for the industry’s future. Key topics will include automotive, embedded solutions, medical electronics, wireless, industrial IoT, cyber security and wearables. When electronica was last held in 2016, it provided more than 73,000 visitors from over 80 countries with 12 halls full of innovations showcased by a total of 2,913 exhibitors from over 50 countries. electronica 2018 will comprise no less than 17 halls to accommodate the demand for extra space from exhibitors. Clearly structured and signposted, electronica will present the electronics industry's entire range of technologies, trends, products and solutions.
The exhibition sectors for electronica 2018 are:
Automotive Displays Electromechanics/System peripherals Electronic Design – ED/EDA Embedded Systems EMS
