Magic Power Technology UK Ltd, the leader in Fanless ATX Power Supplies has just launched its new website featuring 100’s of models from just 1W through to 425W. All products are manufactured under strict quality procedures to ISO 9001:2000 with medical devices also conforming to EN 60601.

Nu Horizons Electronics has extended its long-standing franchise agreement with Murata Power Solutions (previously known as C&D Technologies) to the European market. The distributor previously held the franchise in North America and Asia. The deal will add DC/DC converters rated from 0.25W to 300W and AC/DC power supplies from 200W to 2kW to the Nu Horizons power offering. Initial design-in activity will focus on point-of-load (POL) converters f...

The latest generation of KPS PCB mountable AC/DC power supplies from Lambda, the KPSA Series, has undergone a further shrink to meet demand for smaller, lightweight AC/DC supplies in fields as diverse as factory automation, telecom and datacom, printers and motor drives, and instrumentation.

Linear Technology has announced the LTC3544, a quad channel, high efficiency, 2.25 MHz, synchronous buck regulator that delivers up to 300mA, dual 200mA and 100mA continuous outputs from a 3mm x 3mm QFN package. Using a constant frequency current mode architecture, the LTC3544 operates from an input voltage range of 2.25V to 5.5V, making it ideal for single-cell Li-Ion/polymer, or multicell alkaline/NiCad/NiMH applications. It can generate output...

PULS UK has announced its QTD20.241 DIN-Rail power supply for use with AC motors and drives. At only 65mm wide and offering 24VDC at 20A this 95% efficient Din-Rail power supply uses existing system power to provide secure DC for control systems. Modern machines typically use maintenance-free AC-motors that are controlled by frequency converters or servo amplifiers. Such controllers have an intermediate DC-bus to which all individual drives are c...

STMicroelectronics has extended its portfolio of power management devices with a new family of flexible and high-performance PWM (Pulse Width Modulation) controllers intended for motherboard and POL (Point of Load) markets. Four new products – L6726A, L6727, L6728 and L6728A – integrate a voltage reference, control logic, gate drivers, monitoring and protection circuits into standard SO-8 or tiny 3x3mm DFN packages. Two of the chips offer add...
