New 500-V Vishay Siliconix N-Channel Power MOSFETs Feature Low RDS(on) and Improved Gate Charge
Vishay Intertechnology, Inc. today released three new 500-V, 12-A n-channel power MOSFETs with ultra-low 0.555-Ω maximum on-resistance at a 10-V gate drive, and an improved gate charge of 48 nC in TO-220, TO-220 FULLPAK, and D2PAK (TO-263) packages.
Quiescent Current 2.5µA, 40V, 350mA(IOUT), 2.2MHz Step-Down DC/DC Converter
Linear Technology has announced the LT3970, a 350mA, 40V step-down switching regulator with integrated boost and catch diodes. Its Burst Mode operation keeps quiescent current under 2.5µA in no load standby conditions. The LT3970's 4.2V to 40V input voltage range makes it ideal for automotive and industrial applications. Its internal 550mA switch can deliver up to 350mA of continuous output current to voltages as low as 1.21V. The LT3970's Burst...
Magna-power Electronics’s UK Representative Telonic Instruments Ltd Announces The New Solar Array Emulation Power Supplies: From 2 Kw To 900 Kw+
Magna-Power Electronics Photovoltaic Power Profile Emulation (PPPE) software automatically calculates solar array voltage and current profiles based on user-defined parameters. These profiles can be sequentially sent to a Magna-Power Electronics' programmable power supply, which will emulate defined characteristics. The user can define a limitless number of profiles to be emulated and sequenced over a given time period.

Saft supports South Africa’s Gautrain World Cup trains
Saft onboard battery systems are helping to ensure the smooth and reliable operation of South Africa’s Gautrain state-of-the-art rapid rail network that opened its first phase just in time for the start of the FIFA World Cup. The Gautrain is a new 80 km link that will serve Gauteng Province, providing a safe, efficient and reliable service to both commuters and airport travellers in the Johannesburg area.
Saft signs a new multi-year LTA with EADS Astrium to power all GEO satellites
Saft has signed a new multi-year LTA (Long Term Agreement) with Astrium to supply the onboard lithium-ion (Li-ion) battery modules for every Eurostar GEO (Geosynchronous Earth Orbit) communications satellite to be built over the next years. This latest LTA renews and extends the previous agreement between Saft and Astrium that commenced in 2006. The new LTA covers the supply of the onboard battery modules, built with Saft’s high-energy VES140 a...
Current Sharing for High Density DC Modules
Paralleling of DC/DC converters is often used to increase the output power capability of a single unit by connecting the outputs of two or more converters in parallel. By connecting the parallel pin of each module together, the units will share the load current equally within a few percent. This paper focuses on how N+M redundancy and Hot Plug-in capability can be achieved
