BUCK BOOST
Linear Technology Corporation introduces the latest device in its family of DC/DC uModule™ regulator systems that can regulate an output voltage from a variable input voltage greater than, less than or equal to the output voltage.
The LTM4607 is designed for higher voltage systems and operates from 4.5VIN to 36VIN, regulates an output voltage from 0.8V to 24V, and delivers output power up to 190W. The LTM4607 integrates a synchronous buck-boost DC/DC controller, four N-channel MOSFETs, input and output bypass capacitors and all compensation circuitry in a 15mm x 15mm x 2.8mm land grid array (LGA) plastic molded package. Only an inductor, feedback and sense resistors, and bulk capacitors are required to implement a very low profile, compact and high efficiency design. The LTM4607 provides a compact regulator solution for applications such as networking, industrial, automotive systems and high power battery-operated devices.
The LTM4607 is offered for operation from -40°C to 85°C temperature range.

Maxcap Doppelschicht-Kondensatoren sind ein neuer elektrischer Energiespeicher mit extrem hohen Volumennutzeffekt, nahezu unbegrenzter Betriebsdauer, schneller Lade/Entlade-Fähigkeit sowie sehr geringem Leckstrom.
Im Gegensatz zu Batterien haben Maxcap DLC’s keine störenden chemischen Reaktionen. Sie können unbeschränkt geladen und entladen werden. Es gibt keinen Memoryeffekt.
Sie zeichnen sich durch eine hohe Energiedichte aus: Bis zu 5,6 F in einer 5,5 Volt-Einheit, sowie bis zu 5,0 F in einer 11-Volt-Einheit. Der Temperaturbereich geht von -25 bis +70 °C, bei der LJ & LT-Serie sogar von -40 bis +85°C.
Kanthal Maxcap DLC’s gibt es in 9 verschiedenen Ausführungen mit den Spannungen 5,5 Volt für CMOS RAMS, Mikroprozessoren, Timer etc., sowie mit 11 Volt als Backup für Relais, Stellglieder und Kleinmotoren.
Kondensatoren mit reduzierten Abmessungen, sehr kleinem ESR oder sehr geringer Selbstentladung ( low leackage current ) sind ebenso verfügbar wie eine SMD – Variante in den Spannungen 3,5 Volt und 5,5 Volt mit einer maximalen Kapazität von 0,47 F.
Da Maxcap DLC’s im Gegensatz zu Batterien keine strombegrenzenden Widerstände oder Überspannungsschutz benötigen, reduzieren sich Material – und Arbeitskosten. Bei diesen Kondensatoren besteht auch bei Kurzschluss keine Explosionsgefahr. Sie sind im Wellenbad lötbar, völlig wartungsfrei und brauchen aufgrund ihrer nahezu unbegrenzten Lebensdauer nicht ausgetauscht zu werden.
Einsatzgebiete sind Memory-Backup-Applikationen, sowie Anwendungen, die eine kurzzeitige Bereitstellung von Spitzenleistung erfordern.

Listed among 10 "Best Hotel Bets in Greece"
Petra Hotel, true to its name, has long been a rock-solid sure thing, and since its renovations completed in 2002 it has been added to the prestigious "Golden List" of the best hotels in all of Greece. This recognizes the care lavished by the Stergiou family on these stylish, spacious apartments -- either one- or two-bedroom -- with handsome bathrooms and (except for one) balconies that enjoy splendorous views of Grikos Bay. Each is simply and handsomely decorated, with the necessities of home plus some local touches. It's a perfect family place, just a 2-minute walk from the beach, but also ideal for couples who wish to enjoy a special moment sipping a drink at Petra's elegant, romantic main veranda. Room service and Internet connections are also among its offerings. In 2002, too, the Stergious introduced an evening prix fixe 4-course meal, offering both choices each night and a daily change of menu; with such delicious appetizers as seafood crepes and main courses as salmon topped with salmon roe and cream, the hotel now offers a special dining experience. All these attractions make the Petra popular, especially in August, so advance reservations are advised. | | | |
