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 av...
