Laurent Dubos, Market Segment Director for Lighting at IPDiA, shows that not only active components can be part of an IC, but also several passive components can be integrated. He demonstrates that besides space savings, quality issues are also a hot topic that need to be looked at and are a reason to use this technology. READ FULL ARTICLE >>>

Abstract: With the wide range of existing capacitors, the end user's requirements are roughly met but most of the capacitors see their performances largely impacted when they are submitted to high temperature .In this paper we present the Silicon Capacitors highly recommended for applications in the geothermal , oil well logging , automotive and military .They can operate in a wide operating temperature range and they withstand temperature up to 250°C, with extremely high insulation resistance and very good stability . These capacitors , already extensively used for years in miniaturized equipment and computers ,feature high miniaturization with a large capacitance to volume ratio , thanks to the IPDiA 3D Silicon technology , extremely stable and reliable even at 100μm thickness . Available in hundreds or thousands of nanofarads , in various sizes and custom configurations ,these capacitors are usable at low frequencies but they are also appropriate for RF applications .The recent progress in the 3D Silicon Capacitor IPDIA technology , which moves the world wide record from 250nF/mm² up to 550nF/mm² , will give even more room to higher integration. This is an ultra key driver to growth for High reliability applications . READ FULL PAPER >>>

Abstract: In this paper we present the operation of the XTR30011 device, a high-temperature, versatile, PWM controller with in-specification performance achieved from -60°C to 230°C using a CMOS SOI process. The circuit features a voltage-mode PWM controller that can be used in Buck-mode converters as well as in Boost, Buck-boost, Push-pull and Flyback. Several functional features are implemented including duty-cycle limitation allowing cycle-by-cycle current limitation, hiccup short-circuit protection and complex functionalities for improved efficiency at low load currents. These advanced features for improved efficiency include automatic synchronous-asynchronous mode transition in Buck-mode, pulse skipping logic with adjustable threshold, low-power mode with capability to receiving the 5V converter output voltage.
