Toshiba Electronics Europe (TEE) has announced a new family of ultra-high-efficiency, high-speed MOSFETs that deliver improvements in trade-off characteristics between low on resistance (RDS(ON)) and low input capacitance (Ciss). The new series will have voltage ratings from 60V to 120V and will allow designers to reduce the size and improve the efficiency and performance of secondary synchronous rectification in switch mode power supplies.

Power units such as laptop adapters, PC power supplies and LED lighting ballasts are likely to become more efficient, cost-effective, reliable and quiet as a result of a new controller launched at APEC 2012 by STMicroelectronics. The new controller for LLC resonant voltage converters, the L6699D, is the first of its type to combine anti-capacitive protection, auto-adaptive dead-time and enhanced safe-start operation.

UNIPOWER LLC has announced the SGH 3000 Series of 650W, 12V Front-Ends designed to satisfy the latest networking and datacom applications that demand smaller size, lower energy consumption and a significantly reduced cost of ownership. The SGH Series has a power density of 17.5W/in³ and efficiency levels to 92%.

Powervation has announced the PV3101, a new single phase digital DC/DC controller featuring the company"s Auto-Control adaptive loop compensation technology. The device uses a proprietary DSP/RISC dual-core architecture with a precision data acquisition engine running advanced control and power management algorithms in firmware.

Cree, a market leader in silicon carbide (SiC) power devices, has expanded its design-in support for the industry’s first commercially-available SiC MOSFET power devices with a fully-qualified SPICE model. Using the new SPICE model, circuit designers will be able to evaluate the benefits of the SiC Z-FET MOSFETs that have been designed to provide a higher level of efficiency than is possible with conventional silicon power switching devices for comparably-rated devices.

By extending input voltage operation from 60V down to as low as 5.0V, the new ZXLD1371 LED driver controller from Diodes Incorporated has been designed to handle as broad a range of applications as possible, including those subject to the greatest variance in input voltage, such as automotive lighting and 12VAC powered systems.

Future Energy Solutions, a division of technical broadline distributor Future Electronics, has released a Plugmeter reference design that will enable the rapid development of electricity metering applications which show consumers their current or recent power usage.

Cree has introduced a series of packaged diodes that deliver what is believed to be the highest blocking voltage available in SiC Schottky technology. The 1700V Z-Rec Schottky diodes are almost able to eliminate the reverse recovery losses suffered in silicon PiN diode alternatives, enabling ultra-efficient, smaller and lighter systems.

TDK-Lambda UK has introduced a new 150W range to its CSS series of AC-DC medical power supplies – the single output CSS150 combines a 4kVac reinforced input-to-output isolation with dual fusing and an input-to-ground isolation of 1.5kVac to meet global 60601-1 2nd & 3rd Editions safety approvals for medical equipment.

Vicor Corporation has unveiled its new IBC Power Simulation tool, an online simulation capability that enables power system designers to interactively model the electrical and thermal performance of intermediate bus converters in application-specific operating conditions and thermal environments. Available to users via Vicor’s PowerBench online design centre, the IBC Power Simulation tool offers greater visibility into key electrical and thermal performance attributes of Intermediate Bus Converters (“IBCs”).
