Recom R-78 switching regulator series
21 June, 2011 byThe existing features of the standard Recom R-78 series of switching regulators (high efficiency, small case size and pin compatibility with 78-series linear regulators) have been improved by adding a higher input voltage range of up to 42 DC and double the output power in the same size case. The R-78C series offers 15 W/cm³ of power.
Standby comfortable but energy inefficient
11 May, 2011 by Reinhard ZimmermannThe former ‘green’ theme of energy efficiency has become a household issue in an energy-conscious society. The old filament bulb disappears step by step, and washing machines and dishwashers have become unsaleable without energy-saving programs. But most industrialised societies waste energy on a massive scale by indulging in comfortable ‘standby mode’ in domestic electronics.
