MIC2299 3.5A Minimum, 2MHz High Brightness LED Driver General 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. The MIC2299 has a brightness pin that allows for a programmable torch mode as well as full flash with a single pin when driving high current LEDs. The MIC2299 implements a constant frequency 2MHz PWM control scheme to make the smallest possible design. The MIC2299’s 2MHz operation avoids signal interference in the AM band. The 2.
