Analog Devices announces the Power by Linear™ LT8364, a current mode, 2MHz step-up DC/DC converter with an internal 4A, 60V switch. It operates from an input voltage range of 2.8V to 60V, and is suitable for applications with input sources ranging from a single-cell Li-Ion battery to multicell battery stacks, automotive inputs, telecom power supplies and industrial power rails.

The LT8364 can be configured as either a boost, SEPIC or an inverting converter. Its switching frequency can be programmed between 300kHz and 2MHz, enabling designers to minimize external component sizes and avoid critical frequency bands, such as AM radio. Furthermore, it offers over 90% efficiency while switching at 2MHz. Burst Mode® operation reduces quiescent current to only 9µA while keeping output ripple below 15mVp-p. The combination of a small 4mm x 3mm DFN or high voltage MSOP-16E package and tiny externals ensures a highly compact footprint while minimizing solution cost.

TDK Corporation introduces the XMS500 series of AC-DC power supplies, rated at 500W output power, with a Class I and Class II (no earth ground connection) construction.  The series conforms to curve B conducted and radiated emissions, with a 6dB margin and has a low leakage current of less than 150µA. 

Designed as a configurable product, engineers can select from multiple standard options, to optimize both system performance and cost, without incurring development charges or minimum purchase quantities.  The options include case styles (including an internal low speed fan), a choice of standby voltage, a 12V fixed or variable speed fan supply, remote on/off, AC fail and single or dual input fuses.  12V, 24V, 36V or 48V nominal outputs are offered, with other voltages upon request.  The product has a five year warranty.

The XMS500 accepts a 90 to 264Vac input, withstanding 300Vac for five seconds and can operate in ambient temperatures of up to +70°C, derating linearly above 50°C by 2.5% per °C. The open frame version measures 102 x 180 x 37mm and the U-channel 107 x 180 x 39.5mm.  The low profile allows installation in systems where space is limited.

Physik Instrumente released a new precision feedback option for its linear stages equipped with direct-drive ironless 3-phase motors. The V-551 family of ultra-precision positioning stages models is equipped with precision crossed roller bearings featuring anti-creep cage assist and excellent guiding accuracy (1µm straightness / flatness per 100mm).

Two types of position feedback systems are available: absolute-measuring encoders providing 2 nanometers resolution and incremental encoders providing 0.2 nanometers resolution with effective 0.5nm minimum incremental motion at the stage platform.

Ironless linear motors are used when high dynamics needs to be combined with extremely smooth motion. They are ideal for applications where extremely constant velocity is required, such as in optics inspection, metrology, photonics, interferometry, and semiconductor test equipment. The frictionless, zero-wear motor drives are also popular in fast automation applications, where reliability and maximum up-time are mission-critical.

CUI's Power Group introduced five new open frame series, ranging from 180 W up to 550 W, to its line of internal ac-dc medical power supplies. Certified to the medical 60601 1 edition 3.1 safety standards for 2 x MOPP applications and 4th edition EMC requirements, the VMS 180, VMS 225, VMS 275, VMS 350, and VMS 550 series feature high efficiency up to 94% and high power densities up to 30 W/in3. The new models are housed in 2 x 4 inch (50 x 101 mm) and 3 x 5 inch (76 x 127 mm) packages with profiles measuring as low as 0.75 inches (19 mm).

All of the new VMS series provide output voltage options from 12 to 58 Vdc, feature wide universal input voltage ranges from 80 to 264 Vac, and offer no-load power consumption as low as 0.5 W. The 180 W to 550 W models also carry an input to output isolation of 4200 Vac with leakage current ratings as low as 0.3 mA at 230 Vac. Operating temperatures range at full load from -40 up to +50°C with forced air cooling, derating to 50% load at +70°C. Additional features include protections for over voltage, over current, and short circuit, power factor correction, and a 12 Vdc/500 mA fan output.

Power Integrations introduced the newest member of its SCALE-iDriver IC family, SID1102K, a single-channel, isolated, IGBT and MOSFET gate driver in a wide-body eSOP package. Featuring a peak drive current of up to 5 A, the new part is able to drive 300 A switches without boosters; external boosters can be used to cost-effectively scale gate current up to 60 A peak. This device provides N-channel drive for both the low and high side booster MOSFET switches which reduces system cost, minimizes switching losses and increases power capability.

Reinforced galvanic isolation is provided by Power Integrations' innovative, solid insulator FluxLink technology which eliminates the need for optocouplers, improving reliability and ruggedness. SCALE-iDriver technology simplifies design and manufacturing by reducing BOM count; complete drivers can be built using a SID1102K IC and just eight external components. Devices deliver system-level protection features including under-voltage lock-out, rail-to-rail stabilized output voltage - from a single supply rail, high common-mode transient immunity and 9.4 mm creepage and clearance.

Bel Power Solutions and Protection announces the 0RQB-C5U54LG, a next generation DC/DC converter with an ultra-wide input range (4:1) and 2250 VDC isolation.

The 0RQB-C5U54LG is a PoE (Power Over Ethernet) quarter brick solution that delivers 162 W overall input voltage range, from 18 VDC to 75 VDC. This feature rich module is fixed-frequency, highly efficient and very compact at only 37 x 59 x 15 mm (1.45 x 2.30 x .59"). C5U54LG was designed to support the IEEE 802.3af standard for power transmitted over LAN cables as well as VoIP for powering IP cameras, sensors, radios and telephones, industrial instruments and controllers and wireless access points. As well, 2250 VDC isolation allows engineers to directly attach the brick baseplate to a cool down surface or heatsink, making additional isolation unnecessary.

Equipped with standard protection features like under voltage lockout, over temperature (OT) protection, OCP, SCP and OVP, Bel Power units come standard with primary side on/off. The 0RQB-C5U54LG meets industrial standard 24 V and telecom standard 48 V, is rated Class2/Category2 and meets the latest IPC-9592B derating requirements. It is fully compliant with ROHS, UL/CSA/IEC60950-1, 2nd +A2 version and designed to accommodate PoE (15 W), PoE+ (30 W) and UPoE (60 W).

The ZXTR2105FQ, ZXTR2108FQ and ZXTR2112FQ regulator transistors announced by Diodes Incorporated are qualified to AEC-Q101 standards for high reliability and are product part approval process (PPAP)-capable. Designed to deliver 5V, 8V, or 12V regulated outputs from nominal battery supplies of 12V or 24V, these regulator transistors are well-suited for powering vehicle electronics. These devices can tolerate battery voltage spikes up to 60V, making possible applications that cannot use standard linear regulators.

By monolithically integrating a transistor, Zener diode, and resistor into a SOT23 package, these regulator transistors reduce component count, which minimizes PCB area and increases system reliability by reducing PCB interconnect. The ZXTR2105FQ is targeted at applications that require a 5V ±5% regulated supply from a 12V battery, e.g., for a stable MCU supply within the required 4.7V to 5.3V supply range. The ZXTR2112FQ is aimed at cars and trucks that have 24V batteries but need a 12V ±10% supply for applications such as the VCC supply for gate driver ICs. All these regulator transistors deliver an output current up to 15mA.

Flex Power Modules announced the launch of the BMR480, a new DC/DC advanced bus converter that targets high-end and high-power applications and can handle 1000W of power and 96.2A of peak current.

Coming in an industry-standard and low-profile quarter-brick-format with dimensions of 58.4 x 36.8 x 12.19mm (2.30 x 1.45 x 0.48 inches), the BMR480 operates from a wide 40V to 60V input voltage range and offers multiple tightly regulated (+/-2.5%) pre-programmed outputs at 10.4V, 12V and 12.5V but can be factory configured at any voltage between 9V-13.2V.

The BMR480 module employs Flex's leading edge Hybrid Regulated Ratio (HRR) technology, which enables better utilization of the powertrain to deliver high-power conversion across its wide input voltage range. In addition, delivering exemplary performance for applications that operate in high ambient temperatures with limited airflow, the module offers power conversion of up to 97% efficiency - at 53V and half load - while also keeping power losses low.
