Request InfoNational SemiconductorNational Semiconductor Corp. has released the LM3553 dual flash LED driver system with an I2C interface for configuring 128 brightness levels and 16 flash safety timer durations. Featuring adjustable overvoltage protection, the device can drive one or more high-current flash LEDs in series in high or lower power modes controlled by an internal register or the FEN pin. It is a fixed-frequency, step-up DC-DC converter with two regulated current sinks, driving loads of up to 1.2 A from a single-cell lithium-ion battery. The driver has applications in mobile phones, personal digital assistants,...See full productRelated content from Photonics MediaWEBINARSPhotonics.com 1/18/2018Fiberguide RARe Motheye Fiber: Random Anti-Reflective (RARe) Nanostructures on Optical Fibers as Replacement for AR CoatingsAnti-reflective (AR) coatings are now entering their second century and have remained virtually unchanged throughout their life.
