Expanding its MacroDens portfolio of DC/DC modules, Ericsson Power Modules has released three PKR modules aimed primarily at powering telecom and datacom transmission systems requiring floating dual outputs, such as line cards and optical transmitters. Similarly, the PKR will also power a wide range of applications in instrumentation and process control that use analogue logic and communication chipsets. With their floating design, the devices’...

XP Power continues to increase the flexibility of its range of AC/DC power supplies with the launch of the MFA350. Believed to be the world’s smallest 350 W power supply, the base platform achieves 11.2 Watts per cubic inch power density. The product is designed specifically for telecom and datacom applications, such as storage area networks, data networking and post-production broadcast equipment. Its design facilitates a multitude of packag...

Power density is an increasingly important consideration in a wide variety of high performance handheld systems like smart phones, GPS systems and portable media players that use high capacity batteries. Addressing this need, a linear charger from AnalogicTech offers the industry’s highest charge-current-to-solution-footprint ratio while the integration of the company’s intelligent digital thermal loop feature enables the host system to use ...

Catalyst Semiconductor has announced the CAT4004, a new four-channel LDD (low dropout driver) designed for emerging, power-conscious portables where the LEDs are driven directly from the battery. With the migration of white LEDs to lower forward voltages, a number of portable applications are now able to drive LEDs directly from the system battery without the need to boost voltage. The new CAT4004 is designed specifically to meet the needs of t...

Schaefer, Inc. has introduced the C/B 4800 Series of 6U DC/ DC and AC/DC converter modules ranging in output power from 2.4kW to 5kW. This robust design uses industrial grade components and provides a high density, space-saving solution for applications in industries such as railway controls and communications equipment (onboard and trackside), military applications, oil rigs applications, fuel cell applications, transportation, tele...

The 8V to 400V input operating voltage of the new MXHV9910 high efficiency offline LED driver from Solid State Supplies gives the device the versatility to handle a very wide range of high brightness LED applications.

Linear Technology has announced the LTC3547, a dual channel, high efficiency, 2.25 MHz, synchronous buck regulator that delivers up to 300mA of continuous output current per channel from a 3mm x 2mm DFN package. Using a constant frequency current mode architecture, the LTC3547 operates from an input voltage range of 2.5V to 5.5V, making it ideal for single cell Li-Ion/Polymer, or multicell alkaline/NiCad/NiMH applications.

Vicor has announced the addition of nine mid-power Mini DC-DC converters to its 300Vdc input family: 100 W models at 2 and 3.3 Vout, 150 W models at 5, 12, 15, 24, 28, 36, and 48 Vout. The modules — which incorporate Vicor’s patented low-noise Zero-Current and Zero-Voltage Switching (ZCS/ZVS) —can be used in a variety of applications, including off-line systems with autoranging front ends, industrial and process control, distributed power, ...
