The new reference designs target applications tha...

Power Integrations fournisseur majeur de circuits intégrés haute tension pour conversion d’énergie à haut rendement, annonce deux familles de circuits pour commande de LED, intégrant une correction de facteur de puissance à étage unique et supportant la gradation à TRIAC dans les applications d’éclairage à semiconducteurs (SSL ou solid state lighting). Les puces LinkSwitch-PH (optimisée pour les systèmes isolés) et LinkSwitch-PL...

Power Integrations announced two families of TRIAC-dimmable, single-stage, power-factor-corrected LED driver ICs targeting solid-state lighting (SSL) applications. LinkSwitch-PH (optimized for isolated systems) and LinkSwitch-PL (optimized for non-isolated systems) deliver flicker-free monotonic TRIAC dimming and a user experience similar to that provided by incandescent illumination.

Power Integrations (Nasdaq: POWI), fournisseur majeur de circuits intégrés de puissance pour conversion d’énergie à haut rendement, lance aujourd’hui TOPSwitch-JX, une famille comprenant 16 circuits de conversion d’énergie à haute intégration, incorporant un MOSFET de puissance de 725 V, et destinés aux alimentations flyback. Leur nouvel algorithme de contrôle multi-mode TOPSwitch-JX maximise le rendement pour toutes les condition...

Power Integrations launched TOPSwitch-JX, a highly integrated family of 16 power conversion ICs incorporating a 725 V power MOSFET for use in flyback power supplies. The novel TOPSwitch-JX multi-mode control algorithm maximizes power efficiency across the entire load range. High efficiency at full power minimizes power wasted during normal operation and reduces the complexity and expense of thermal management on the system. At low power levels, h...

Power Integrations today launched its new EuP Standards Finder, an online tool for power supply designers. Providing immediate access to specific requirements of the European Commission’s EuP Ecodesign Directive, this tool eliminates the need for designers to search through volumes of data to figure out what is relevant to them.

Power Integrations today launched Version 7.1.5 of its popular PI Expert power supply design software.
