National Semiconductor Corp. (Santa Clara, CA) introduced new SolarMagicTM integrated circuits (ICs) to reduce cost, improve reliability, and simplify design of photovoltaic (PV) systems. Ranging from a 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.
