Linear Technology annonce le LT3743, un convertisseur DC/DC, abaisseur, synchrone, conçu pour fournir un courant continu pour piloter des DEL de forte intensité. La gamme de tensions d’entrée du composant, de 5,5 V à 36 V, le rend idéal dans une grande variété d’applications incluant l’éclairage industriel, la projection DLP (Digital Light Processing), et l’éclairage architectural. Le LT3743 délivre un courant continu de DEL jus...

Linear Technology annonce le LTC3787, un contrôleur DC/DC élévateur, synchrone, à une sortie et deux phases, de forte puissance, dans lequel les diodes élévatrices sont remplacées par des MOSFET canal N de haut rendement. Ceci permet de supprimer le radiateur normalement requis dans les convertisseurs élévateurs de puissances moyennes à élevées. Le LTC3787 peut fournir une tension de sortie de 24 V à 10 A, à partir d’une tension ...

Linear Technology introduces the LTC4353, a 0V to 18V dual ideal diode controller that replaces two high power Schottky diodes, enabling low loss ORing of multiple power sources with minimal disturbance to supply voltages.

Yamaichi Electronics has announced the TF junction box for thin film modules. The TF junction box for thin film modules by Yamaichi Electronics is the first thin film junction box that has kink protection with Hermetic Sealed technology. This is the first time this familiar technology has been used in a junction box.

Linear Technology has announced the LT3595, a 45V 2MHz DC/DC buck mode converter designed to operate as a 16-channel constant current LED driver. Each channel of the LT3595 can drive up to ten 50mA LEDs in series, enabling the LT3595 to drive up to 160 50mA LEDs while delivering efficiencies up to 92%. Its multichannel capability makes it ideal for large TFT-LCD backlighting applications. Each of the 16 channels is independently operated and can ...

Molex has announced the HyperJack PoE+ Power Source Equipment (PSE), Integrated Connector Module (ICM). Available in 2x4 and 2x6 configurations, the HyperJack modules feature a fully integrated design that reduces the engineering effort allowing for plug-and-play Power over Ethernet Plus (PoE+) without investing in development of PoE+ capability.

Vishay Intertechnology (NYSE: VSH) today introduced six new FRED Pt hyperfast rectifiers for consumer electronics applications. The new 600-V, 8-A devices feature an ultra-low typical voltage drop of 1 V at rated current, fast recovery times as low as 16 ns in hard switching conditions, and typical leakage current at 125 °C as low as 30 µA.

Vishay Intertechnology, Inc. today announced a major portfolio expansion for its TMBS rectifiers utilizing Trench MOS Barrier Schottky technology. Released today were 20 new 45 V devices in four power package types and featuring a wide range of current ratings from 10 A to 60 A.

NEC Electronics Europe has introduced a series of uncooled 1310nm Multiple Quantum Wells (MQW) structured Distributed Feed-Back (DFB) laser diodes allowing the operation up to 95°C and low power consumption. The NX8346-series transmitter optical sub-assembly (TOSA) is based on a new AlGaInAs chip design allowing high temperature and high speed operation. Due to an oxidation free BH-structure, low operating currents (Iop) and high reliability are...

With its new transmitter optical sub assembly (TOSA) series Mitsubishi Electric has developed four 1.3µm band laser modules for optical transmission at speeds of 10Gb/s and, respectively, 8Gb/s. Each individual module fits into an enhanced 8.5 and 10 Gigabit small form factor pluggable module (SFP+) measuring just 13.3mm x 13.4mm x 56.5mm. Compared to XFP (10 Gigabit small factor pluggable module) the SFP+ compliant transceivers are 60 percent...
