National Semiconductor introduces new SolarMagic ICs

15 APRIL 2011

National Semiconductor Corp. introduced ten new SolarMagic integrated circuits (ICs), the first in a series developed to reduce cost, improve reliability and simplify design of photovoltaic (PV) systems. Ranging from the industry’s first full-bridge gate driver to a micropower voltage regulator, the new ICs are well-suited for a variety of photovoltaic electronic applications, including those found in microinverters, power optimizers, charge controllers and panel safety systems. The new SolarMagic ICs are the first developed to meet photovoltaic renewable energy-grade qualification requirements. Each IC is engineered specifically for demanding rooftop environments that range from extreme cold to severe heat, and each passes rigorous testing with enhanced reliability specific to solar requirements. In addition, the ICs ensure long-term operation, developed to meet and exceed the 25-year life expectancy of photovoltaic modules. Collectively provided as a complete design, SolarMagic ICs increase energy harvest, reduce cost per kilowatt-hour and improve safety in junction boxes and other types of enclosures. Used independently, the ICs provide high voltage and high current gate drive for microinverter or power optimizer designs. A full set of reference designs and application notes help the designer quickly develop a complete photovoltaic system.
