High voltage power supply offers lower power dissipation
The LTC3256, a highly integrated, high voltage low noise dual output power supply, which takes a single positive input and generates 5 and 3.3V step-down supplies with high efficiency and no inductors has been announced by Linear Technology. The device features a wide 5.5-38V input voltage range and includes independently enabled dual outputs: a 5V 100mA supply, and a 250mA 3.3V LDO regulator, for a total of 350mA available output current.
Transient voltage suppressors target tablets & laptops
The new VTVSxxASMF series of surface-mount transient voltage suppressor (TVS) protection diodes from Vishay are now available at Rutronik. They are the industry’s first to feature a 2% breakdown voltage tolerance. They are ideal for line transient voltage protection in space-constrained electronics, such as laptops, notebooks, tablets, smartphones, and external hard drives.
36W wall plug PSUs comply with latest energy standards
Expanding its range of wall mounted plug-in power supplies, XP Power has announced the VEL and VER series. These wall plug PSUs provide a wide range of power levels and meeting the energy efficiency and no load requirements of the new DoE Energy Efficiency Level VI and the EU CoC Tier 2 standards.
Lightning current arresters safely handle up to 50kA
The FLT-SEC-PLUS 264 type 1 lightning current arresters from Phoenix Contact are used in main supplies with 230/400V networks. Even in the event of high lightning currents up to 50kA per position, systems are protected and can continue running unaffected. Thanks to Safe Energy Control (SEC) technology, the protective devices feature high performance and durability.
1A buck DC/DCs offer ±1% accuracy for multi-rail systems
Linear Technology Corporation announces the LTC3374A, a highly integrated general-purpose power management solution for systems requiring multiple low voltage power supplies. The device can be configured to provide 2 to 8 independent regulated outputs with 15 possible output current configurations.
AC-DC power supplies boast power density of 8.5W per cubic inch
Qualstar’s N2Power branded XR160 and XR160RE AC-DC power supplies are in stock at Luso Electronics. These ultra-small power supplies provide the highest power density in the market at their rated 160W power output.

Rittal publishes guide to new low voltage directive
A new European Directive will provide greater protection for users of electrical equipment across a wide range of consumer and professional products, including power supply units and components such as fuses. The Low Voltage Directive (LVD) 2014/35/EU came into force on 20 April 2016, replacing Directive 2006/95/EC. It provides detailed and in-depth guidance around the placing of electrical equipment within certain voltage boundaries.
