New superjunction MOSFETs support energy-saving power topologies
STMicroelectronics’ new MDmesh™ M6 series of 600V superjunction transistors provide high efficiency in medium-power resonant and hard-switching converter topologies.
The threshold voltage, which is optimized for soft switching, makes the new transistors ideal for LLC resonant converters and boost-PFC converters in energy-conscious applications. MDmesh M6 devices also perform efficiently in hard-switching topologies.
Efficient DC-DC converter for telecoms equipment
Murata Power Solutions has released the 1kW DRQ-11.4/88-L48 series of quarter brick, intermediate bus DC-DC converter modules, to meet the growing power requirements of high-reliability networking and telecoms equipment.
The fully regulated modules provide an output voltage of 11.4V at 88A from an input voltage ranging between 36V and 60V DC. This fully regulated, fixed-frequency 1kW bus converter offers industry-leading efficiency of 97%. It conforms to the standard DOSA high-power quarter brick specification.
12W medical power adaptor complies with US and EU efficiency standards
MEAN WELL has released a 12W medical-grade wall plug adapter. The GSM12E/U series of wall-mount adapters comes with mains plug options suitable for either EU (E Type) or North American (U Type) applications.
The GSM12 adapters comply with the specifications of the US Department of Energy’s Level VI and the European Union’s ErP efficiency regulations. They provide isolation consistent with two Means of Patient Protection (MOPP). Leakage current is <100μA. They are qualified to the European EN60601-1-11 and the North American ANSI/AAMI ES60601-1-11 home healthcare safety standards.
