N2Power's 330W AC/DC power supply achieves up to 90% efficiency
N2Power, a division of Qualstar Corporation, has developed a new 330W AC/DC power supply that features an industry-leading level of power density and efficiency. The 1.35- inch high, open-frame XL330-54 has a 3-inch x 5.3-inch (76mm x 135mm) footprint and is able to deliver a power density of 15W/in3 with only 13CFM cooling, a space saving of 32% compared to typical 1U units of similar rating, most of which have a 6-inch x 4-inch (102mm x 152mm) footprint.
Its maximum full-load efficiency of 90%, achieved through synchronous rectification, Or- ing MOSFETs and an active PFC design, means that the XL330-54 generates 23% less heat than most comparable power supplies, minimising cooling requirements and increasing system reliability. The high efficiency delivers energy savings throughout the product's life, providing greater return on investment.
The XL330-54 has two primary outputs: 54V/6.1A and 12V/9A, plus a 12V/1A auxiliary output. The 54V output is 2250VDC isolated from the other outputs making it Power-over- Ethernet (PoE) compatible. The design allows active current sharing on the 54V output for up to four power supplies to be operated in parallel. N+1 operation can also be configured. Other features of the power supplies include universal AC input (90-264VAC) and active
inrush current protection of 10.5A at 240VAC, which does not change
during operation. The XL330-54 CS is RoHS compliant and meets all major international safety and EMC requirements. N2Power's Vice President and General
Manager, Randy Johnson, said, "With the rising price of energy across the globe, engineers now appreciate that efficiency gains of just a few percentage points deliver substantial cost benefits throughout a product's operating life. For example, when a power supply is 90% efficient, rather than 87% efficient, that's a 23% performance improvement and energy saving. N2Power delivers this improvement without compromising the product's compact size or other desirable features."

Latest DC/DC converter modules from Powersolve meet EN50155 for rail applications
Power supply specialist Powersolve has announced the TEP160WIR series of high performance DC/DC converter modules that provide up to 182W. Approval to EN50155 allows these new converters to be used in railway applications with an ultra-wide 4:1 input voltage range (up to 160VDC), efficiency levels to 91% and adjustable output voltages also make the new converters suitable for a wide range of applications. There are 15 models in the range with output voltages ranging from 12 to 48VDC and they can be PCB, chassis or DIN-Rail mounted (with adaptor plate) making them ideal for use in industrial environments. Connection is by screw terminals for chassis and DIN Rail versions.
Housed in a shielded metal case with an aluminium baseplate, the converters are suitable for temperatures of -40°C to +75°C with an optional heatsink. Manufactured by Traco, TEP160WIR
Intersil expands “HIP” bridge driver portfolio
Intersil Corporation has expanded its “HIP” portfolio of MOSFET bridge drivers for power supply and motor drive applications. This family of 100V, 2A, high frequency half-bridge drivers provides the shortest rise/fall times, adjustable dead-time control and flexible control outputs.
The HIP2120, HIP2121, HIP2122 and HIP2123
products provide more flexibility to control the half-bridge MOSFETs and to reduce the component count of the application circuit. Additionally, the integrated delay timer allows designers to adjust the dead-time between the two outputs via an external resistor, eliminating

the shoot-through current that can occur in half- bridge and synchronous buck topologies. The new drivers are designed for telecom isolated half-bridge DC/DC converters, non-isolated DC/DC converters, motor drivers, Class-D amplifiers and a variety of other applications.
