The National Semiconductor (National Semiconductor) announced the launch of a series of 10 brand new SolarMagic integrated circuits, its advantage is that it can reduce solar system power cost and improve the operation stability and simplify the circuit design. The launch of the new series chip has the first of the whole bridge type poly line drive, also have micro power voltage stabilizer, applicable to the solar system in different kinds of electronic devices, including miniature converter, power optimization device, charging controller and panels and other security device.

New SolarMagic chip accord with solar renewable energy attestation standard, and through elaborate design, can ensure that such discretion on the roof of the temperature differences still harsh environment normal operation; Through the strict stability testing to ensure that efficiency is more stable and reliable and comply with the solar energy system operation requirement. In addition, this series chip can long-term operation, apply to life expectancy of 25 years or more than 25 years of solar modules. Built-in SolarMagic chip solar system which can improve the generating capacity, and reduce unit costs, and make sure that electricity wiring and other more secure and reliable sealing device. SolarMagic chips used independently, miniature converter or power optimization device can provide higher poly line driven voltage and current.

National semiconductor also provide complete reference design and application instructions, to help the system design engineers can quickly completed entire solar system circuit design. Each reference designs each has specialized testing circuit boards, materials list and diagram. National semiconductors on June 8 to 10 in Munich of solar photoelectric exhibition show all series SolarMagic chip.

National semiconductor and provide two models SM72441 and SM72442 respectively of the most high power conversion program MPPT tracking control technology (solar energy system controller, let the distributed power optimization is to add the maximum power conversion tracking function. The two chip has different features, including the voltage and current diagnosis, four built-in switch boost/buck converter control functions, over voltage/over-current protection and the I2C interface connection, and other functions.

SM72295 bridge type poly line to drive and SM72482 double channel 5A composite poly line drive can support power optimization device, miniature converter and charge control power handling circuit, as well as drive 4 adopts full bridge type configuration, and the discrete type MOSFET both of the drive built-in high electric end over-current detect amplifier and can launch/flow back to large current.

National semiconductor and as a drive power optimization device, miniature converter and different kinds of bias charge control system to provide power supply SM72485 conduction time constant switching voltage stabilizer, its characteristic is homework voltage up, and have high phase failure is 100V switching power efficiency. National semiconductor also provide the power consumption can reduce system SM72238 5V low pressure drop regulator.

National semiconductor solar system specifically for the distributed power optimization transmitters and battery chargers have widely adopted auxiliary circuit supply much money different chip products for support, let this kind of application can add detection, sensor and supervision and control functions including equipped with monitoring the reset circuit function SM72240 chip, double channel micro power to rail tracks input CMOS comparator SM72375, accurate and can be preset temperature switches and sensor SM72480, and suitable for a wide range of power supply voltage of the high accuracy CMOS rail rail input/output amplifier SM72501 etc.

10 brand new SolarMagic chip USES a variety of standard packaging, have already started mass production supply.
