Description
General part information
MIC2299 Series
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. The feedback voltage is only 200mV, minimizing power dissipation in constant-current 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.
