The 16mm x 10mm x 4mm, 41-pin, QFN package is simple to solder onto a printed circuit board and provides for a compact, low-profile point-of-load design. The devices’ feature sets comprise power good, adjustable soft start, tracking, synchronisation, programmable UVLO, prebias start-up, selectable auto or FPWM modes, as well as overcurrent and overtemperature protection. The modules can be configured as negative output voltage for inverting applications.

Typical environments include industrial, Medical and Test Equipment, General Purpose Wide V_IN Regulation, and Inverted Output Applications.

The devices offer unique features such as low offset 40µV (maximum), low offset drift (2µV/C maximum) high slew rate (18V/µs), and high capacitive load drive at up to 500pF. These characteristics make the device excellent for high-voltage industrial applications. The device allows operation in single-supply applications via the common-mode range of the internal op-amp that reaches to the negative supply. The device has the option to operate on single (4.5V to 36V) or dual supplies (±2.25V to ±18V).

The device offers a difference amplifier for the base of many common circuits, and without employing an expensive precision resistor network. The device is specified for operation over the extended industrial temperature range of –40C to +125C, and is offered in an 8-pin VSSOP surface-mount package.

The company has built an ecosystem with partner companies, particularly to serve its customers in producing innovative power-management solutions in areas such as battery management systems. Visitors to the stand will see designs created by industrial partner Stercom Power Solutions, providing expertise in advanced battery management systems tailored for energy storage applications. Also shown will be innovative open platforms from the Fraunhofer IISB, which has created the foxBMS. This has been formulated as the ultimate open source development platform for battery management, applicable to industrial systems such as energy storage and guided vehicles (ESS/AGVs) and automotive applications (EV/HEVs).

A demonstration will show the company’s offering for system integrators and designers operating in the field of energy storage in high power systems, where they are challenged to deliver ever-higher levels of conversion efficiency. The demonstration will feature a reference design for a 30kW DC-DC charger for high power energy storage, developed by partner Stercom. The power converter is a high voltage, high-frequency design employing SiC technology that targets both static energy storage and electric vehicles, yielding 99% power conversion efficiency resulting in a 30% smaller charging unit.

Company specialists will be available to engage in discussions around today’s power conversion technology challenges, at all levels. The company’s partner program offers a route to efficient turnkey solutions while, for designers seeking to optimise high voltage, high-frequency power converter circuit topologies, the company’s staff will be available for in-depth discussions. Areas of special interest include isolated gate driving, and power management ICs (PMICs). They can provide a high-performance combination of parts that will optimise the output of chargers and inverters based on SiC and GaN power MOSFETs. Pairing digital iCoupler technology with innovative PMICs results in designs with lowest EMI and highest efficiency. The company’s product family offers a fully characterised route to fastest time-to-market, with lowest R&D risks.

The company will engage in the Exhibitor Forum series of technical presentations at PCIM 2019. At 13:40 on 7th May, ADI’s Stefano Gallinaro will deliver a talk entitled “Battery Management for Energy Storage Systems: innovations in the ecosystem”. The Forum is located in Hall 7/507.

These converter modules are entirely encapsulated with terminal strip connections and furnished with integrated filters which restrict conducted and radiated emissions (EN 55032 class A) and improve the modules EMC immunity (EN 55035) without the necessity for any external components. The 6W TMDC modules measure only 2.09” x 1.34” x 1.04” and the 10W TMDC 10 modules measure only 3.11” x 1.34” x 0.87”. Each family comprises 14 modules giving either 9-36VDC or 18-75VDC input ranges and outputs of 5, 12, 15, 24, ±12, ±15, ±24VDC with high-efficiency operation up to 86%. Remote ON/Off control and Power Good LED Indicator round out the functionality of these modules. Full-load convection-cooled operation from -40C to +80C, high reliability >4.1 million hours and international safety approvals to UL 62368-1 with CB Report make these excellent solutions for a broad range of industrial applications and environments.

For industrial applications, the PKE8000A series offers highly reliable, high-performance and rugged DC-DC solutions in the industry-standard 2″ x 1″ form factor, operating from 12V, 24V or 48V supply voltages thanks to its ultra-wide-input range of 9V to 75V. Giving up to 40W of output power at up to 91% efficiency, the series also provides MTBF of up to four million hours and input-to-output isolation of 2250VDC. The devices satisfy the latest IEC/EN/UL62368-1 safety standards.

For railways applications, the PKE7000A series is packaged in the same 2 x 1″ industry-standard form factor, but this time works from a 43V to 160V input, producing up to 30W. This makes it ideal for the bulk of onboard demands running from 72V and/or 110V nominal supplies, most often found in the railways sector. The devices comply with the EN50155 railway standard and offer MTBF figures of up to five million hours to meet the most exacting applications.

Olle Hellgren, director of Product Management and Business Development at Flex Power Modules, commented: “The PKE-A series is just one of a wide range of new products we are introducing to support Industrial and Railways applications, and is a crucial part of our previously announced push into these important market segments.”
