The A8295, A8297 and A8298 from Allegro MicroSystems Europe are the latest generation of devices in a family of single and dual low-noise block (LNB) supply and control voltage regulator ICs designed for use in satellite receivers in set-top boxes and LCD television sets.

NEC Electronics Europe today announced its participation in the «SPS / IPC / DRIVES 2007» exhibition being held November 27 – 29 at the Nuremberg Messe. The NEC Electronics booth will be featuring the company’s solutions for Profinet, industrial motor control and HMIs.

Keithley Instruments, Inc. announces a new C-V measurement instrument for its powerful Model 4200-SCS Semiconductor Characterization System. The Model 4200-CVU instrument comes as a module that plugs into any available instrument slot of the Model 4200-SCS, allowing fast and easy capacitance measurements from femtoFarads (fF) to nanoFarads (nF), at frequencies from 10kHz to 10MHz.

Lambda has launched a new version of its popular FPS1000 front end power supply with a nominal output voltage of 12V , ideal for driving non-isolated point of load dc-dc converters directly in systems utilising a distributed power architecture without the need for intermediate bus conversion.

The new A8512 from Allegro MicroSystems Europe is a multi-output white LED RGB driver IC for the LED backlighting of large-area LCD monitors and television screens. The new device integrates a scalable-output boost controller operating in constant-frequency current mode control - adjustable between 300 kHz and 1 MHz - driving an external MOSFET. It integrates six internal current sinks each capable of sinking up to 80 mA, which can be combined to...

The A4930 from Allegro MicroSystems Europe is a single-phase brushless DC motor pre-driver integrated circuit designed to control high-current devices such as fans, blowers or pumps with supply voltages from 8 V to 36 V.

The A8295, A8297 and A8298 from Allegro MicroSystems Europe are the latest generation of devices in a family of single and dual low-noise block (LNB) supply and control voltage regulator ICs designed for use in satellite receivers in set-top boxes and LCD television sets.

Linear Technology présente le LTC4227 , un contrôleur Hot Swap compact, à diode idéale double, qui offre un contrôle PowerPath et un contrôle des courants d’appel pour les alimentations redondantes, de 2,9 V à 18 V. Le LTC4227 régule la chute de tension directe dans deux MOSFET canal N externes, pour assurer un partage du courant entre les alimentations dans les applications à circuits OU à diodes.

Linear Technology Corporation annonce une nouvelle version de grande fiabilité (classe MP), du LTC4441, un pilote de grille de MOSFET canal N, 6 A, qui fonctionne avec une température de jonction de – 55°C à 125°C. Ce pilote, de forte puissance, est conçu pour augmenter la puissance de sortie et le rendement d’un contrôleur DC/DC, lui permettant de piloter des MOSFET canal N, de forte puissance, ou plusieurs MOSFET en parallèle.

Linear Technology Corporation présente le LTC3867, un contrôleur DC/DC abaisseur, synchrone, à fréquence fixe, avec contrôle non-linéaire, détection de tension différentielle de sortie et synchronisation par horloge. Le contrôle non-linéaire réduit l’amplitude de la tension de sortie, lors de la survenue d’événements transitoires dans la charge, en augmentant la fréquence de fonctionnement, ce qui permet au LTC3867 de se rétab...
