Murata Power Solutions has announced the introduction of the NMUSB2022PMC, a surface mount powered data isolator module that conveniently provides dual port USB data and power isolation from a single upstream port. When used in conjunction with a USB host, a single NMUSB202PMC module counts as two USB hubs for cascaded applications and provides full 5V/500mA power to each downstream port. 250 VRMS reinforced isolation provides safety, immunity to EMI and breaking of ground loops.
The is NMUSB2022PMC is fully compliant with USB 2.0 specification, which enables hassle-free, “plug and play” operation with any USB-compatible device. It can do automatic switching between full-speed (12 Mbps) and low speed (1.5 Mbps) operation. Operating temperature ranges from -40°C to +85°C.
The device enables USB isolation function with a single SMT component. Users may power any USB compatible device from the NMUSB module. The data isolation function included with the DC-DC module adds value and convenience to the user and also eases system approval for medical systems safety certifications. Applications include industrial control for isolating sensors and medical environments, where USB is becoming common for low cost sensing and communication but isolation is necessary for safety and noise immunity. It is also well suited for harsh environment data communication and sensor communications.

Vicor has released its next generation of DCMs with a family of wide input range (43 V to 154 V input) 3623 (36 mm x 23mm) ChiPs with power levels up to 240 W and 93% efficiency, targeted at new rail transportation and infrastructure applications. Modern rail infrastructure requires a wide range of DC-DC converters to power a variety of new services for both freight and commuter markets.
Commuter rail systems require mobile office communication capabilities with the infotainment capabilities of home. Freight rail systems require monitoring and control capabilities to assure the safe and timely delivery of all goods onboard. While both commuter and freight systems demand reliable and high-performance power systems for the necessary safety and security measures (onboard and at station.)
The DCM is an isolated, regulated DC-DC converter module that can operate from an unregulated, wide range input to generate an isolated DC output. These new ChiP DCMs simplify power system designs by supporting multiple input voltage ranges in a single ChiP. With efficiencies up to 93% in a ChiP package less than 1.5 in2, these DCMs offer engineers leading density and efficiency.

Aimtec has announced the release of two new series of regulated AC to DC power converters, the AME10-BJZ and AME20-BJZ. These new series will expedite and simplify industrial and commercial product design in a low cost solution. The new regulated 10 W and 20 W AME10-BJZ and AME20-BJZ series are packaged in industry standard packages: 62.0 x 45.0 x 30.0 mm (2.44 x 1.77 x 1.18 inches) and 70.00 x 48.00 x 30.0 mm (2.76 x 1.89 x 1.18 inches) respectively. They meet the IEC/EN 62368-1 standards and are EN55032 class B compliant.
The internal EMC filtering reduces the need for external filtering components reducing production costs and are well suited for a wide range of applications including electric metering of three phase AC supply, industrial applications as well as commercial equipment applications. The standard package is available with 3.3, 5, 9, 12, 15 and 24 VDC outputs. These series offer over current, over voltage and short circuit protection while accepting an ultra-wide input range of 90-528 VAC or 100-745 VDC at 47-63 Hz input frequency. This series offers a high MTBF of 300,000 hours with an efficiency of up to 83%. The new AME10-BJZ and AME20-BJZ series feature high input/output isolation of 4,000 VAC and operate from a bone chilling -40°C to a blistering +70°C with full power output from -10°C to +55°C.

MINMAX Technology has announced the MINMAX MAU01M / MSCU01M series, a new range of high performance 1 W medical safety approved DC-DC converters with encapsulated SIP-7 & SMD packages. They are specifically designed for medical applications. The series includes models available for input voltages of 4.5 VDC to 5.5 VDC, 10.8 VDC to 13.2 VDC, and 21.6 to 26.4 VDC. The I/O isolation is specified for 4,000 VAC with reinforced insulation and ated for a 300 Vrms working voltage.
Further features include short circuit protection, a low leakage current of 2 μA max. and operating ambient temperating range of -40°C to 95°C. This is achieved without de-rating and with a high efficiency of up to 84%. The MAU01M / MSCU01M series conforms to the 4th edition medical EMC standard. It meets 2xMOPP (Means of Patient Protection) per 3rd edition of IEC/EN 60601-1 & ANSI/AAMI ES60601-1. The MAU01M / MSCU01M series offer an economical solution for demanding medical instrument applications that require a certified supplementary and reinforced insulation system to comply with latest medical safety approvals under the 2x MOPP requirements.
