MIC2299 Description
The MIC2299 is a high power boost-switching regulator that is optimized for constant-current control. The MIC2299 is capable of driving up to 2 series 1A white LED for photoflash and other applications. The feedback voltage is only 200mV, minimizing power dissipation in constantcurrent control applications, and hence extends battery life.
