Description

  • Typical Application for MIC2299: 3.5A Minimum, 2MHz High Brightness LED Driver. The MIC2299 is a high power boost-switching regulator that is optimized for constant-current control. The MIC2299 is capable of driving up to two series 1A white LED for photoflash and other applications.
